Our study is done in the minimal left-right symmetric model assuming a type-II dominance scenario with charge conjugation as the left-right symmetry. We then show that the 0\u03bd\u03b2\u03b2 decay rate may be dominated by the contribution proportional to this LR mixing, which at the hadronic level induces the leading-order contribution to the interaction between two pions and two charged leptons. The resulting long-range pion exchange contribution can significantly enhance the decay rate compared to previously considered short-range contributions. Finally, we find that even if future cosmological experiments rule out the inverted hierarchy for neutrino masses, there are still good prospects for a positive signal in the next generation of 0\u03bd\u03b2\u03b2 decay experiments.", "date": "2021-04-16", "date_type": "published", "publication": "Physical Review Letters", "volume": "126", "number": "15", "publisher": "American Physical Society", "pagerange": "Art.

", "abstract": "We study discovery prospects for a real triplet extension of the Standard Model scalar sector at the Large Hadron Collider (LHC) and a possible future 100 TeV pp collider. We focus on the scenario in which the neutral triplet scalar is stable and contributes to the dark matter relic density. When produced in pp collisions, the charged triplet scalar decays to the neutral component plus a soft pion or soft lepton pair, yielding a disappearing charged track in the detector. We recast current 13 TeV LHC searches for disappearing tracks, and find that the LHC presently excludes a real triplet scalar lighter than 248 (275) GeV, for a mass splitting of 172 (160) MeV with \u2112 = 36 fb\u207b\u00b9. The reach can extend to 497 (520) GeV with the collection of 3000 fb\u207b\u00b9. We extrapolate the 13 TeV analysis to a prospective 100 TeV pp collider, and find that a \u223c 3 TeV triplet scalar could be discoverable with \u2112 = 30 ab\u207b\u00b9, depending on the degree to which pile up effects are under control. We also investigate the dark matter candidate in our model and corresponding present and prospective constraints from dark matter direct detection. We find that currently XENON1T can exclude a real triplet dark matter lighter than \u223c 3 TeV for a Higgs portal coupling of order one or larger, and the future XENON20T will cover almost the entire dark matter viable parameter space except for vanishingly small portal coupling.", "date": "2021-01", "date_type": "published", "publication": "Journal of High Energy Physics", "volume": "2021", "number": "1", "publisher": "Springer", "pagerange": "Art.

", "abstract": "Determining the thermal history of electroweak symmetry breaking (EWSB) is an important challenge for particle physics and cosmology. Lattice simulations indicate that EWSB in the Standard Model (SM) occurs through a crossover transition, while the presence of new physics beyond the SM could alter this thermal history. The occurrence of a first order EWSB transition would be particularly interesting, providing the needed pre-conditions for generation of the cosmic matter-antimatter asymmetry and sources for potentially observable gravitational radiation. I provide simple, generic arguments that if such an alternate thermal history exists, the new particles involved cannot be too heavy with respect to the SM electroweak temperature, nor can they interact too feebly with the SM Higgs boson. These arguments do not rely on the decoupling limit. I derive corresponding quantitative expectations for masses and interaction strengths which imply that their effects could in principle be observed (or ruled out) by prospective next generation high energy colliders. The simple, generic arguments provide a quantitative, parametric understanding of results obtained in a wide range of explicit model studies; relate them explicitly to the electroweak temperature; and delineate broad contours of collider phenomenology pertaining to a non-standard history of EWSB.", "date": "2020-09", "date_type": "published", "publication": "Journal of High Energy Physics", "volume": "2020", "number": "9", "publisher": "Springer", "pagerange": "Art.

", "abstract": "We introduce a scenario for CP-violating (CPV) dark photon interactions in the context of non-abelian kinetic mixing. Assuming an effective field theory that extends the Standard Model (SM) field content with an additional U(1) gauge boson (X) and a SU(2_)L triplet scalar, we show that there exist both CP-conserving and CPV dimension five operators involving these new degrees of freedom and the SM SU(2)_L gauge bosons. The former yields kinetic mixing between the X and the neutral SU(2)_L gauge boson (yielding the dark photon), while the latter induces CPV interactions of the dark photon with the SM particles. We discuss experimental probes of these interactions using searches for permanent electric dipole moments (EDMs) and di-jet correlations in high-energy pp collisions. It is found that the experimental limit on the electron EDM currently gives the strongest restriction on the CPV interaction. In principle, high energy pp collisions provide a complementary probe through azimuthal angular correlations of the two forward tagging jets in vector boson fusion. In practice, observation of the associated CPV asymmetry is likely to be challenging.", "date": "2020-04-01", "date_type": "published", "publication": "Physical Review D", "volume": "101", "number": "7", "publisher": "American Physical Society", "pagerange": "Art.

", "abstract": "We present the first end-to-end nonperturbative analysis of the gravitational wave power spectrum from a thermal first-order electroweak phase transition (EWPT), using the framework of dimensionally reduced effective field theory and preexisting nonperturbative simulation results. We are able to show that a first-order EWPT in any beyond the Standard Model (BSM) scenario that can be described by a Standard Model-like effective theory at long distances will produce gravitational wave signatures too weak to be observed at existing and planned detectors. This implies that colliders are likely to provide the best chance of exploring the phase structure of such theories, while transitions strong enough to be detected at gravitational wave experiments require either previously neglected higher-dimension operators or light BSM fields to be included in the dimensionally reduced effective theory and therefore necessitate dedicated nonperturbative studies. As a concrete application, we analyze the real singlet-extended Standard Model and identify regions of parameter space with single-step first-order transitions, comparing our findings to those obtained using a fully perturbative method. We discuss the prospects for exploring the electroweak phase diagram in this model at collider and gravitational wave experiments in light of our nonperturbative results.", "date": "2019-12-01", "date_type": "published", "publication": "Physical Review D", "volume": "100", "number": "11", "publisher": "American Physical Society", "pagerange": "Art.

We focus on the reach for choices of parameters yielding a strong first order electroweak phase transition. The event selection follows the 4b analysis by the ATLAS Collaboration, enhanced with the use of a boosted decision tree method to optimize the discrimination between signal and background events. The output of the multivariate discriminant is used directly in the statistical analysis. The prospective reach of the 4b channel is compatible with previous projections for the bb\u03b3\u03b3 and 4\u03c4 channels for heavy Higgs boson mass m\u2082 below 500 GeV and superior to these channels for m\u2082>500\u2009\u2009GeV.

We derive the most general, renormalizable scalar potential, assuming the presence of the Standard Model Higgs doublet, H, and an electroweak multiplet \u03a6 of arbitrary SU(2)_L rank and hypercharge, Y. We show that, in general, the \u03a6-H Higgs portal interactions depend on three, rather than two independent couplings as has been previously considered in the literature. For the phenomenologically viable case of Y = 0 multiplets, we focus on the septuplet and quintuplet cases, and consider the interplay of relic density and spin-independent direct detection cross section. We show that both the relic density and direct detection cross sections depend on a single linear combination of Higgs portal couplings, \u03bb_(eff). For \u03bb_(eff) \u223c O(1), present direct detection exclusion limits imply that the neutral component of a scalar electroweak multiplet would comprise a subdominant fraction of the observed DM relic density.", "date": "2019-08", "date_type": "published", "publication": "Journal of High Energy Physics", "volume": "2019", "number": "8", "publisher": "Springer", "pagerange": "Art.

", "abstract": "We propose a novel dispersive treatment of the so-called inner radiative correction to the neutron and nuclear \u03b2 decay. We show that it requires knowledge of the parity-violating structure function F^((0))_3 that arises from the interference of the axial vector charged current and the isoscalar part of the electromagnetic current. By isospin symmetry, we relate this structure function to the charged current inelastic scattering of neutrinos and antineutrinos. Applying this new data-driven analysis we obtain a new, more precise evaluation for the universal radiative correction \u0394^(V,new)_R=0.02467(22) that supersedes the previous estimate by Marciano and Sirlin, \u0394^V_R=0.02361(38). The substantial shift in the central value of \u0394^V_R reflects in a respective shift of V_(ud) and a considerable tension in the unitarity constraint on the first row of the Cabibbo-Kobayashi-Maskawa matrix which is used as one of the most stringent constraints on new physics contributions in the charged current sector. We also point out that dispersion relations offer a unifying tool for treating hadronic and nuclear corrections within the same framework. We explore the potential of the dispersion relations for addressing the nuclear structure corrections absorbed in the Ft values, a crucial ingredient alongside \u0394^V_R in extracting V_(ud) from superallowed nuclear decays. In particular, we estimate the quenching of the free neutron Born contribution in the nuclear environment, corresponding to a quasielastic single-nucleon knockout, and find a significantly stronger quenching effect as compared to currently used estimates based on the quenching of spin operators in nuclear transitions. This observation suggests that the currently used theoretical uncertainties of Ft values might be underestimated and require a renewed scrutiny, while emphasizing the importance of new, more precise measurements of the free neutron decay where nuclear corrections are absent.", "date": "2019-07-01", "date_type": "published", "publication": "Physical Review D", "volume": "100", "number": "1", "publisher": "American Physical Society", "pagerange": "Art.

We focus specifically on the trilepton final state in regions of parameter space yielding prompt decays of the right-handed gauge bosons (W_R) and neutrinos (N_R). In the minimal LRSM, the Dirac Yukawa couplings are completely fixed in terms of the mass matrices for the heavy and light neutrinos. In this case, the trilepton signal provides a direct probe of the Dirac mass term for a fixed W_R and N_R mass.

We show that for the simplest type-II seesaw scenario, CLFV searches have the greatest sensitivity.

The baryon asymmetry is therefore produced exclusively through the electroweak mechanism in the intermediate phase. We illustrate this scenario with a simple model that reproduces the observed baryon asymmetry.

Above the electroweak scale v, the d_t arises from two gauge invariant operators generated at a scale \u039b\u226bv that also mix with the light fermion EDMs under renormalization group evolution at two-loop order. Bounds on the EDMs of first generation fermion systems thus imply bounds on |d_t|. Working in the leading log-squared approximation, we find that the present upper bound on |d_t| is 10^(\u221219) e cm for \u039b=1 TeV, except in regions of finely tuned cancellations that allow for |d_t| to be up to fifty times larger.

We find that the parameter space consistent with a strong first-order electroweak phase transition (SFOEWPT) and present dark matter phenomenological constraints is significantly restricted compared to results of a conventional, gauge-noninvariant analysis. In the simplest variant of the cxSM, recent LUX data and a SFOEWPT require a dark matter mass close to half the mass of the standard model-like Higgs boson.

When these couplings arise from chiral-symmetry-breaking charge-parity-violating (CP-violating) operators, such as the QCD \u03b8 term or quark chromoelectric dipole moments, one may relate hadronic matrix elements entering the PVTV couplings to nucleon and pion mass shifts by exploiting the corresponding chiral transformation properties at leading order in the chiral expansion. We compute the higher order contributions to the lowest order relations arising from chiral loops and next-to-next-to leading order operators. We find that, for the QCD \u03b8 term, the higher order contributions are analytic in the quark masses, while for the quark chromoelectric dipole moments and chiral-symmetry-breaking four-quark operators, the matching relations also receive nonanalytic corrections.

", "abstract": "Searches for supersymmetry at the Large Hadron Collider (LHC) have significantly constrained the parameter space associated with colored superpartners, whereas the constraints on color-singlet superpartners are considerably less severe. In this study, we investigate the dependence of slepton decay branching fractions on the nature of the lightest supersymmetric particle (LSP). In particular, in the Higgsino-like LSP scenarios, both decay branching fractions of \u2113~L and \u03bd~\u2113 depend strongly on the sign and value of M_1/M_2, which has strong implications for the reach of dilepton plus E_T searches for slepton pair production. We extend the experimental results for same flavor, opposite sign dilepton plus E_T searches at the 8TeV LHC to various LSP scenarios. We find that the LHC bounds on sleptons are strongly enhanced for a non-Bino-like LSP: the 95% C.L. limit for m\u2113_L extends from 300 GeV for a Bino-like LSP to about 370 GeV for a Wino-like LSP. The bound for \u2113_L with a Higgsino-like LSP is the strongest (\u223c 490 GeV) for M_1/M_2 \u223c \u2212 tan^2 \u03b8_W and is the weakest (\u223c 220 GeV) for M_1/M_2 \u223c tan^2 \u03b8_W . We also calculate prospective slepton search reaches at the 14 TeV LHC. With 100 fb^(\u22121) integrated luminosity, the projected 95% C.L. mass reach for the left-handed slepton varies from 550 (670) GeV for a Bino-like (Winolike) LSP to 900 (390) GeV for a Higgsino-like LSP under the most optimistic (pessimistic) scenario.

Recent work has used the g_\u03c0^(1)-induced one-loop contribution to the neutron electric dipole moment d_n, together with the present experimental d_n bound, to constrain the CP-violating parameters of the left-right symmetric model. We show that this and related analyses are based on an earlier meson theory d_n computation that is not consistent with the power-counting appropriate for an effective field theory. We repeat the one-loop calculation using heavy baryon chiral perturbation theory and find that the resulting d_n sensitivity to g_\u03c0^(1) is suppressed, implying more relaxed constraints on the parameter space of the left-right symmetric model. Assuming no cancellations between this loop contribution and other contributions, such as the leading order EDM low-energy constant, the present limit on d_n implies |g_\u03c0^(1)|\u22721.1\u00d710^(\u221210).", "date": "2014-09-07", "date_type": "published", "publication": "Physics Letters B", "volume": "736", "publisher": "Elsevier", "pagerange": "147-153", "id_number": "CaltechAUTHORS:20141017-082629056", "issn": "0370-2693", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20141017-082629056", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "SCOAP3" }, { "agency": "Deutsche Forschungsgemeinschaft (DFG)" }, { "agency": "National Natural Science Foundation of China" }, { "agency": "Department of Energy (DOE)", "grant_number": "DE-AC02-05CH11231" }, { "agency": "Department of Energy (DOE)", "grant_number": "DE-FG02-08ER41531" }, { "agency": "Department of Energy (DOE)", "grant_number": "DE-SC0011095" } ] }, "doi": "10.1016/j.physletb.2014.07.014", "primary_object": { "basename": "1-s2.0-S0370269314005000-main.pdf", "url": "https://authors.library.caltech.edu/records/sej32-bkt89/files/1-s2.0-S0370269314005000-main.pdf" }, "related_objects": [ { "basename": "1401.5366v2.pdf", "url": "https://authors.library.caltech.edu/records/sej32-bkt89/files/1401.5366v2.pdf" } ], "resource_type": "article", "pub_year": "2014", "author_list": "Seng, Chien-Yeah; de Vries, Jordy; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/yjc6d-z6h46", "eprint_id": 50741, "eprint_status": "archive", "datestamp": "2023-08-20 02:50:33", "lastmod": "2023-10-18 14:27:11", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "Mantry-S", "name": { "family": "Mantry", "given": "Sonny" } }, { "id": "Pitschmann-M", "name": { "family": "Pitschmann", "given": "Mario" } }, { "id": "Ramsey-Musolf-M-J", "name": { "family": "Ramsey-Musolf", "given": "Michael J." }, "orcid": "0000-0001-8110-2479" } ] }, "title": "Distinguishing axions from generic light scalars using electric dipole moment and fifth-force experiments", "ispublished": "pub", "full_text_status": "public", "note": "\u00a9 2014 American Physical Society.\n\nReceived 11 March 2014; published 16 September 2014.\n\nWe acknowledge fruitful discussions with H.

These constraints are compared to those derived from direct searches in fifth-force experiments and from combining laboratory searches with astrophysical bounds on stellar energy loss. For axion-mediated TVPV spin-dependent forces, EDM constraints dominate over fifth-force limits by several orders of magnitude. However, we show that for a generic light scalar, unrelated to the strong CP problem, present bounds from direct fifth-force searches are more stringent than those inferred from EDM limits for the interaction ranges explored by fifth-force experiments.

Experimental searches exclude top squarks across a wide range of masses, but a gap remains when the difference between the masses of the stop and the lightest supersymmetric particle is close to the top mass. We propose to search for stops in this regime by exploiting the azimuthal angular correlation of forward tagging jets in (s)top pair production. As shown in earlier work, this correlation is sensitive to the spin of the heavy states, allowing one to distinguish between top and stop pair production. Here, we demonstrate that this angular information can give a statistically significant stop pair production signal in the upcoming LHC run.

", "abstract": "Searches for the permanent electric dipole moments (EDMs) of molecules, atoms, nucleons and nuclei provide powerful probes of CP violation both within the Standard Model and beyond the Standard Model (BSM). The interpretation of experimental EDM limits requires careful delineation of physics at a wide range of scales, from the long-range atomic and molecular scales to the short-distance dynamics of physics at or beyond the Fermi scale. In this review, we provide a framework for disentangling contributions from physics at these disparate scales, building out from the set of dimension four and six effective operators that embody CP violation at the Fermi scale. We survey computations of hadronic and nuclear matrix elements associated with Fermi-scale CP violation in systems of experimental interest and quantify the present level of theoretical uncertainty in these calculations. Using representative BSM scenarios of current interest, we discuss ways in which the interplay of physics at various scales can generate EDMs at a potentially observable level.", "date": "2013-07", "date_type": "published", "publication": "Progress in Particle and Nuclear Physics", "volume": "71", "publisher": "Elsevier", "pagerange": "21-74", "id_number": "CaltechAUTHORS:20130809-084130584", "issn": "0146-6410", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20130809-084130584", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Department of Energy (DOE)", "grant_number": "DE-FG02-97ER41019" }, { "agency": "Department of Energy (DOE)", "grant_number": "DE-FG02-08ER41531" }, { "agency": "Department of Energy (DOE)", "grant_number": "DE-FG02-04ER41338" }, { "agency": "NSF", "grant_number": "PHY-1152096" }, { "agency": "Wisconsin Alumni Research Foundation" }, { "agency": "Universit\u00e9 Paris Sud Attractivit\u00e9" } ] }, "doi": "10.1016/j.ppnp.2013.03.003", "primary_object": { "basename": "1303.2371v1.pdf", "url": "https://authors.library.caltech.edu/records/5hr94-4ct04/files/1303.2371v1.pdf" }, "resource_type": "article", "pub_year": "2013", "author_list": "Engel, Jonathan; Ramsey-Musolf, Michael J.; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/91acp-s4968", "eprint_id": 39826, "eprint_status": "archive", "datestamp": "2023-08-22 09:43:02", "lastmod": "2023-10-24 17:13:49", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "Cirigliano-V", "name": { "family": "Cirigliano", "given": "Vincenzo" } }, { "id": "Ramsey-Musolf-M-J", "name": { "family": "Ramsey-Musolf", "given": "Michael J." }, "orcid": "0000-0001-8110-2479" } ] }, "title": "Low energy probes of physics beyond the standard model", "ispublished": "pub", "full_text_status": "public", "keywords": "Fundamental symmetries; Neutrinos; Beyond the standard model", "note": "\u00a9 2013 Elsevier B.V.\n\nSubmitted - 1304.0017v1.pdf

We analyze the sensitivity of these probes to the different couplings Z\u2032u\u0305 q (q=u, c, t) and Z\u2032d\u0305 q (q=d, s, b) in a model-independent way that can be applied to any specific Z\u2032 scenario. We show that constraints from neutral kaon and heavy flavor studies preclude significant contributions from flavor nondiagonal couplings except for those involving top quarks. We apply our results to a light Z\u2032 with flavor diagonal couplings to up or down quarks, a scenario proposed in the literature to explain the CDF W plus dijet anomaly. We find that such a particle would not affect the C_1q coefficients, but it would have a sizable impact on C_2q couplings that can be probed by future measurements of parity-violating deep inelastic scattering of polarized electrons off of deuterium.", "date": "2013-03-14", "date_type": "published", "publication": "Physical Review D", "volume": "87", "number": "5", "publisher": "American Physical Society", "pagerange": "Art.

The two dimension-five operators, i.e., the quark EDM and quark chromo-EDM, produce contributions to d_\u03c1 whose coefficients are of the same sign and within a factor of 2 in magnitude. Moreover, should a suppression mechanism be verified for the \u03b8 term in any beyond-Standard-Model theory, the contribution from a four-quark operator can match the quark EDM and quark chromo-EDM in importance.

Given this range, a case may be made for new physics beyond the Standard Model (SM) because of the resultant vacuum stability problem, i.e., the SM Higgs quartic coupling may run to negative values at a scale below the Planck scale. We study representative minimal extensions of the SM that can keep the SM Higgs vacuum stable to the Planck scale by introducing new scalar or fermion interactions at the TeV scale while solving other phenomenological problems. In particular, we consider the type-II seesaw model, which is introduced to explain the nonzero Majorana masses of the active neutrinos. Similarly, we observe that if the stability of the SM Higgs vacuum is ensured by the running of the gauge sector couplings, then one may require a series of new electroweak multiplets, the neutral component of which can be a cold dark matter candidate. Stability may also point to a new U(1) gauge symmetry, in which the SM Higgs carries a nonzero charge.", "date": "2012-12-28", "date_type": "published", "publication": "Physical Review D", "volume": "86", "number": "11", "publisher": "American Physical Society", "pagerange": "Art.

We find that resonant sfermion sources can in principle provide a large enough baryon asymmetry in various corners of the sfermion parameter space, and we focus, in particular, on the case of large tan\u03b2, where third-generation down-type (s)fermions become relevant. We show that in the case of top squark and sbottom sources, the viable parameter space is ruled out by constraints from the nonobservation of the Mercury electric dipole moment.

A particularly interesting case occurs when the potential barrier separating the broken and symmetric vacua of a spontaneously broken symmetry is produced by tree-level terms in the potential. Here, we study this scenario in a simple Abelian Higgs model, for which the gauge-invariant potential is known, augmented with a singlet real scalar. We analyze the possible symmetry-breaking patterns in the model, and illustrate in which cases gauge artifacts are expected to manifest themselves most severely.

If instead no new physics appears until higher energy scales, there may be significant tension between the vacuum stability analysis and phenomenological constraints (in particular electroweak precision data) to the extent that the complex singlet extension with light Higgs and singlet masses would be ruled out.

", "abstract": "We analyze the dispersion correction to elastic parity violating electron-proton scattering due to \u03b3Z exchange. In particular, we explore the theoretical uncertainties associated with modeling contributions of hadronic intermediate states. Taking into account constraints from low- and high-energy, parity-conserving electroproduction measurements, choosing different models for contributions from the nonresonant processes, and performing the corresponding flavor rotations to obtain the electroweak amplitude, we arrive at an estimate of the uncertainty in the total contribution to the parity-violating asymmetry. At the kinematics of the Q-Weak experiment, we obtain a correction to the asymmetry equivalent to a shift in the proton weak charge of (0.0054\u00b10.0020). This should be compared to the value of the proton's weak charge of QW^p=0.0713\u00b10.0008 that includes Standard Model contributions at tree level and one-loop radiative corrections. Therefore, we obtain a new Standard Model prediction for the parity-violating asymmetry in the kinematics of the Q-Weak experiment of (0.0767\u00b10.0008\u00b10.0020_(\u03b3Z)). The latter error leads to a relative uncertainty of 2.8% in the determination of the proton's weak charge and is dominated by the uncertainty in the isospin structure of the inclusive cross section. We argue that future parity-violating inelastic ep asymmetry measurements at low to moderate Q^2 and W^2 could be exploited to reduce the uncertainty associated with the dispersion correction. Because the corresponding shift and error bar decrease monotonically with decreasing beam energy, a determination of the proton's weak charge with a lower-energy experiment or measurements of \"isotope ratios\" in atomic parity violation could provide a useful cross-check on any implications for physics beyond the Standard Model derived from the Q-Weak measurement.", "date": "2011-07", "date_type": "published", "publication": "Physical Review C", "volume": "84", "number": "1", "publisher": "American Physical Society", "pagerange": "Art.

We reformulate the Bjorken-Wolfenstein argument in\n a matter suitable for the interpretation of experiments planned at the\n Thomas Jefferson National Accelerator Facility (JLab). In particular,\n we observe that because the contribution of the relevant twist-four\n operator satisfies the Callan-Gross relation, the ratio of\n parity-violating longitudinal and transverse cross sections, R^(\u03b3Z),\n is identical to that for purely electromagnetic scattering, R^\u03b3, up\n to perturbative and power-suppressed contributions. This result\n simplifies the interpretation of the asymmetry in terms of other\n possible novel hadronic and electroweak contributions. We use the\n results of MIT Bag Model calculations to estimate contributions of the\n relevant twist-four operator to the leading term in the asymmetry as a\n function of Bjorken x and Q^2.

", "abstract": "We analyze the potential sensitivity of a search for e \u2192 \u03c4 conversion at a proposed electron-ion collider (EIC) facility. To that end, we calculate the cross sections for e \u2192 \u03c4 events in a leptoquark framework assuming that the leptoquark masses are on the order of several hundred GeV or more. Given present limits on leptoquarks from direct searches at HERA and rare decay processes, an EIC sensitive to 0.1 fb e \u2192 \u03c4 cross sections could probe previously unexplored regions of parameter space for these lepton flavor violating events (assuming 90 GeV center-of-mass energy and 10 fb^(\u22121) integrated luminosity). Depending on the species of leptoquark and flavor structure of the couplings, an EIC search could surpass the HERA and rare process sensitivity to e \u2192 \u03c4 conversion amplitudes by as much as an order of magnitude or more. We also derive updated limits on quark flavor-diagonal LFV leptoquark interactions using the most recent BaBar \u03c4 \u2192 e\u03b3 search. We find that limits from an EIC e \u2192 \u03c4 search could be competitive with the most recent \u03c4 \u2192 e\u03b3 limit for a subset of the quark flavor-diagonal leptoquark couplings. Using an SU(5) GUT model in which leptoquark couplings are constrained by theneutrino masses and mixing, we illustrate how observable leptoquark-induced e \u2192 \u03c4 conversion can be consistent with stringent LFV limits imposed by \u2192 e\u03b3 and e conversion searches.", "date": "2010-11", "date_type": "published", "publication": "Journal of High Energy Physics", "volume": "2010", "number": "11", "publisher": "Springer", "pagerange": "Art.

We identify the four CP-violating phases that are individually highly constrained by current EDM bounds, and we explore how these phases and correlations among them are constrained by current EDM limits. We also analyze the prospective implications of the next generation of EDM experiments. We point out that all other CP-violating phases in the MSSM are not nearly as tightly constrained by limits on the size of EDMs. We emphasize that a rich set of phenomenological consequences is potentially associated with these generically large EDM-allowed phases, ranging from B physics, electroweak baryogenesis, and signals of CP-violation at the CERN Large Hadron Collider and at future linear colliders. Our numerical study takes into account the complete set of contributions from one-and two-loop EDMs of the electron and quarks, one-and two-loop Chromo-EDMs of quarks, the Weinberg 3-gluon operator, and dominant 4-fermion CP-odd operator contributions, including contributions which are both included and not included yet in the CPsuperH2.0 package.

", "abstract": "A long-range intergalactic force between dark matter (DM) particles, mediated by an ultralight scalar, is tightly constrained by galactic dynamics and large scale structure formation. We examine the implications of such a ''dark force\" for several terrestrial experiments, including E\u00f6tv\u00f6s tests of the Weak Equivalence Principle (WEP), direct-detection DM searches, and collider studies. The presence of a dark force implies a nonvanishing effect in E\u00f6tv\u00f6s tests that could be probed by current and future experiments depending on the DM model. For scalar DM that is a singlet under the standard model gauge groups, a dark force of astrophysically relevant magnitude is ruled out in large regions of parameter space by the DM relic density and WEP constraints. WEP tests also imply constraints on the Higgs-exchange contributions to the spin-independent (SI) DM-nucleus direct-detection cross section. For WIMP scenarios, these considerations constrain Higgs-exchange contributions to the SI cross section to be subleading compared to gauge-boson mediated contributions. In multicomponent DM scenarios, a dark force would preclude large shifts in the rate for Higgs decay to two photons associated with DM-multiplet loops that might otherwise lead to measurable deviations at the LHC or a future linear collider. The combination of observations from galactic dynamics, large scale structure formation, E\u00f6tv\u00f6s experiments, DM-direct-detection experiments, and colliders can further constrain the size of new long-range forces in the dark sector.", "date": "2010-03-15", "date_type": "published", "publication": "Physical Review D", "volume": "81", "number": "6", "publisher": "American Physical Society", "pagerange": "Art.

We identify an illustrative \"lepton-mediated electroweak baryogenesis\" scenario in which the baryon asymmetry is induced mainly through the presence of a left-handed leptonic charge. We derive analytic formulas for the computation of the baryon asymmetry that, in light of these effects, are qualitatively different from those in the established literature.

From a cosmological standpoint, we point out that regions of parameter space that over-produce relic lightest supersymmetric particles can be salvaged only by assuming a dilution of the particle relic density that makes it compatible with the dark matter density: this dilution must occur after dark matter freeze-out, which ordinarily takes place after electroweak baryogenesis, implying the same degree of dilution for the generated baryon number density as well. We expand on previous studies on the viable MSSM regions for baryogenesis, exploring for the first time an orthogonal slice of the relevant parameter space, namely the (tan \u03b2, m_A) plane, and the case of non-universal relative gaugino-higgsino CP violating phases. The main result of our study is that in all cases lower limits on the size of the electric dipole moments exist, and are typically on the same order, or above, the expected sensitivity of the next generation of experimental searches, implying that MSSM electroweak baryogenesis will be soon conclusively tested.", "date": "2010-01-04", "date_type": "published", "publication": "Journal of High Energy Physics", "volume": "2010", "number": "1", "publisher": "Springer", "pagerange": "Art.

We also find that vacuum stability requirements may place a lower bound on the singlet dark matter mass for given singlet quartic self coupling, leading to restrictions on the parameter space consistent with the observed relic density.

In particular, we generalize existing approaches to distinguish between chemical potentials of particles and their superpartners. This allows us to test the assumption of superequilibrium (equal chemical potentials for particles and sparticles) that has usually been made in earlier studies. We show that in the Minimal Supersymmetric Standard Model, superequilibrium is generically maintained \u2014 even in the absence of fast supergauge interactions \u2014 due to the presence of Yukawa interactions. We provide both analytic arguments as well as illustrative numerical examples. We also extend the latter to regions where analytical approximations are not available since down-type Yukawa couplings or supergauge interactions only incompletely equilibrate. We further comment on cases of broken superequilibrium wherein a heavy superpartner decouples from the electroweak plasma, causing a kinematic bottleneck in the chain of equilibrating reactions.

", "abstract": "The properties of light leptoquarks predicted in the context of a simple grand unified theory and their observability at the LHC are investigated. The SU(5) symmetry of the theory implies that the leptoquark couplings to matter are related to the neutrino mass matrix. We study the resulting connection between neutrino masses and mixing parameters and the leptoquark decays, and show that different light neutrino hierarchies imply distinctive leptoquark decay signatures. We also discuss low-energy constraints implied by searches for charged lepton flavour violation, studies of meson decays, and electroweak precision data. We perform a detailed parton-level study of the leptoquark signals and the Standard Model backgrounds at the LHC. With the clean final states containing a di-lepton plus two jets, the QCD production of the leptoquark pair can be observed for a leptoquark mass of one TeV and beyond. By examining the lepton flavor structure of the observed events, one could further test the model predictions related to the neutrino mass spectrum. In particular, b-flavor tagging will be useful in distinguishing the neutrino mass pattern and possibly probing an unknown Majorana phase in the Inverted Hierarchy or the Quasi-Degenerate scenario. Electroweak associated production of the leptoquark doublet can also be useful in identifying the quantum numbers of the leptoquarks and distinguishing between the neutrino mass spectra, even though the corresponding event rates are smaller than for QCD production. We find that with only the clean channel of \u03bc+E/_T+jets, one could expect an observable signal for a leptoquark masses of about 600 GeV or higher.", "date": "2009-09-21", "date_type": "published", "publication": "Nuclear Physics B", "volume": "819", "number": "1-2", "publisher": "Elsevier", "pagerange": "139-176", "id_number": "CaltechAUTHORS:20090917-084726022", "issn": "0550-3213", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20090917-084726022", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Department of Energy (DOE)", "grant_number": "DE-FG02-08ER41531" }, { "agency": "Wisconsin Alumni Research Foundation" }, { "agency": "Department of Energy (DOE)", "grant_number": "DE-FG02-95ER40896" }, { "agency": "Ministry of Education (China)" } ] }, "doi": "10.1016/j.nuclphysb.2009.04.009", "primary_object": { "basename": "0810.4138", "url": "https://authors.library.caltech.edu/records/pkrft-72r84/files/0810.4138" }, "resource_type": "article", "pub_year": "2009", "author_list": "P\u00e9rez, Pavel Fileviez; Han, Tao; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/qnddx-grs67", "eprint_id": 14870, "eprint_status": "archive", "datestamp": "2023-08-20 02:15:29", "lastmod": "2023-10-18 20:04:42", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "Carroll-S-M", "name": { "family": "Carroll", "given": "Sean M." }, "orcid": "0000-0002-4226-5758" }, { "id": "Mantry-S", "name": { "family": "Mantry", "given": "Sonny" } }, { "id": "Ramsey-Musolf-M-J", "name": { "family": "Ramsey-Musolf", "given": "Michael J." }, "orcid": "0000-0001-8110-2479" }, { "id": "Stubbs-C-W", "name": { "family": "Stubbs", "given": "Christopher W." }, "orcid": "0000-0003-0347-1724" } ] }, "title": "Dark-matter-induced violation of the weak equivalence principle", "ispublished": "pub", "full_text_status": "public", "note": "\u00a9 2009 The American Physical Society.\nReceived 30 July 2008; revised 15 October 2008; published 1 July 2009.\nWe thank J.

", "abstract": "It is conventional wisdom that successful electroweak baryogenesis in the Minimal Supersymmetric extension of the Standard Model (MSSM) is in tension with the non-observation of electric dipole moments (EDMs), since the level of CP-violation responsible for electroweak baryogenesis is believed to generate unavoidably large EDMs. We show that CP-violation in the bino\u2013Higgsino sector of the MSSM can account for successful electroweak baryogenesis without inducing large EDMs. This observation weakens the correlation between electroweak baryogenesis and EDMs, and makes the bino-driven electroweak baryogenesis scenario the least constrained by EDM limits. Taking this observation together with the requirement of a strongly first-order electroweak phase transition, we argue that a bino-driven scenario with a light stop is the most phenomenologically viable MSSM electroweak baryogenesis scenario.", "date": "2009-03-09", "date_type": "published", "publication": "Physics Letters B", "volume": "673", "number": "1", "publisher": "Elsevier", "pagerange": "95-100", "id_number": "CaltechAUTHORS:20090624-111707631", "issn": "0370-2693", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20090624-111707631", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Department of Energy (DOE)", "grant_number": "DE-FG02-08ER41531" }, { "agency": "Department of Energy (DOE)", "grant_number": "DE-FG02-04ER41268" }, { "agency": "Wisconsin Alumni Research Foundation" } ] }, "doi": "10.1016/j.physletb.2009.02.004", "primary_object": { "basename": "0811.1987", "url": "https://authors.library.caltech.edu/records/tcffe-mgq58/files/0811.1987" }, "resource_type": "article", "pub_year": "2009", "author_list": "Li, Yingchuan; Profumo, Stefano; et el." }, { "id": "https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/h189w-kpj12", "eprint_id": 14329, "eprint_status": "archive", "datestamp": "2023-08-20 01:05:54", "lastmod": "2023-10-18 16:29:17", "type": "article", "metadata_visibility": "show", "creators": { "items": [ { "id": "Fileviez-P\u00e9rez-Pavel", "name": { "family": "Fileviez P\u00e9rez", "given": "Pavel" }, "orcid": "0000-0001-7201-5840" }, { "id": "Patel-Hiren-H", "name": { "family": "Patel", "given": "Hiren H." }, "orcid": "0000-0002-2582-6189" }, { "id": "Ramsey-Musolf-M-J", "name": { "family": "Ramsey-Musolf", "given": "Michael J." }, "orcid": "0000-0001-8110-2479" }, { "id": "Wang-Kai", "name": { "family": "Wang", "given": "Kai" }, "orcid": "0000-0003-1661-689X" } ] }, "title": "Triplet scalars and dark matter at the LHC", "ispublished": "pub", "full_text_status": "public", "note": "\u00a9 2009 The American Physical Society. \n\nReceived 1 December 2008; published 31 March 2009. \n\nWe thank T.

Depending on the symmetries of the scalar potential, such extensions may provide a viable candidate for the observed relic density of cold dark matter or a strong first order electroweak phase transition needed for electroweak baryogenesis. Using the simplest extension of the SM scalar sector with one real singlet field, we analyze the generic implications of a singlet-extended scalar sector for Higgs boson phenomenology at the Large Hadron Collider (LHC). We consider two broad scenarios: one in which the neutral SM Higgs and singlet mix and the other in which no mixing occurs and the singlet can be a dark matter particle. For the first scenario, we analyze constraints from electroweak precision observables and their implications for LHC Higgs phenomenology. For models in which the singlet is stable, we determine the conditions under which it can yield the observed relic density, compute the cross sections for direct detection in recoil experiments, and discuss the corresponding signatures at the LHC.", "date": "2008-02-01", "date_type": "published", "publication": "Physical Review D", "volume": "77", "number": "3", "publisher": "American Physical Society", "pagerange": "Art.

The theoretical interpretation of such experiments, however, requires careful implementation of a well-known theorem by Schiff that implies a vanishing net EDM for an atom built entirely from pointlike, nonrelativistic constituents that interact only electrostatically. Any experimental observation of a nonzero atomic EDM would result from corrections to the pointlike, nonrelativistic, electrostatic assumption.

We show that the more general Schiff moment operator reduces to the previously employed operator only under certain approximations that are not generally justified.

This contribution can be calculated in a model independent way. In the absence of fine-tuning, we find that current neutrino mass limits imply that \u00b5v < 10^\u201314 Bohr magnetons.

In the minimal supersymmetric standard model (MSSM), these contributions give rise to couplings between Higgs and fermion supermultiplet densities, thereby communicating the effects of CP-violation in the Higgs sector to the baryon sector. We show that the decay and inverse decay-induced contributions that arise at zeroth order in the strong coupling, alphas, can be substantially larger than the [script O](alphas) terms that are generated by scattering processes and that are usually assumed to dominate. We revisit the often-used approximation of fast Yukawa-induced processes and show that for realistic parameter choices it is not justified. We solve the resulting quantum transport equations numerically with special attention to the impact of Yukawa rates and study the dependence of the baryon-to-entropy ratio YB on MSSM parameters.", "date": "2006-06-01", "date_type": "published", "publication": "Physical Review D", "volume": "73", "number": "11", "publisher": "American Physical Society", "pagerange": "Art.

We show how symmetries of the 0nubetabeta-decay quark operators arising in a given particle physics model determine the form of the corresponding effective, hadronic operators. We classify the latter according to their symmetry transformation properties as well as the order at which they appear in a derivative expansion. We apply this framework to several particle physics models, including R-parity violating supersymmetry (RPV SUSY) and the left-right symmetric model (LRSM) with mixing and a right-handed Majorana neutrino. We show that, in general, the pion exchange contributions to 0nubetabeta decay dominate over the short-range four-nucleon operators.

In particular, we show how a nonzero mixing angle zeta in the left-right symmetry model produces a new potentially dominant contribution to 0nubetabeta decay that substantially modifies previous limits on the masses of the right-handed neutrino and boson stemming from constraints from 0nubetabeta decay and vacuum stability requirements.", "date": "2003-08", "date_type": "published", "publication": "Physical Review D", "volume": "68", "number": "3", "publisher": "American Physical Society", "pagerange": "Art.

", "abstract": "We address the physics implications of a precise determination of the weak charge of the proton, QW(p), from a parity violating elastic electron proton scattering experiment to be performed at the Jefferson Laboratory. We present the standard model (SM) expression for QW(p) including one-loop radiative corrections, and discuss in detail the theoretical uncertainties and missing higher order QCD corrections. Owing to a fortuitous cancellation, the value of QW(p) is suppressed in the SM, making it a unique place to look for physics beyond the SM. Examples include extra neutral gauge bosons, supersymmetry, and leptoquarks. We argue that a QW(p) measurement will provide an important complement to both high energy collider experiments and other low energy electroweak measurements. The anticipated experimental precision requires the knowledge of the O(alphas) corrections to the pure electroweak box contributions. We compute these contributions for QW(p), as well as for the weak charges of heavy elements as determined from atomic parity violation.", "date": "2003-07-01", "date_type": "published", "publication": "Physical Review D", "volume": "68", "number": "1", "publisher": "American Physical Society", "pagerange": "Art.

", "abstract": "Nuclear anapole moments are parity-odd, time-reversal-even E1 moments of the electromagnetic current operator. Although the existence of this moment was recognized theoretically soon after the discovery of parity nonconservation (PNC), its experimental isolation was achieved only recently, when a new level of precision was reached in a measurement of the hyperfine dependence of atomic PNC in 133Cs. An important anapole moment bound in 205Tl also exists. In this paper, we present the details of the first calculation of these anapole moments in the framework commonly used in other studies of hadronic PNC, a meson-exchange potential that includes long-range pion exchange and enough degrees of freedom to describe the five independent S-P amplitudes induced by short-range interactions. The resulting contributions of \u03c0, \u03c1, and \u03c9 exchange to the single-nucleon anapole moment, to parity admixtures in the nuclear ground state, and to PNC exchange currents are evaluated, using configuration-mixed shell-model wave functions. The experimental anapole moment constraints on the PNC meson-nucleon coupling constants are derived and compared with those from other tests of the hadronic weak interaction. While the bounds obtained from the anapole moment results are consistent with the broad \"reasonable ranges\" defined by theory, they are not in good agreement with the constraints from the other experiments. We explore possible explanations for the discrepancy and comment on the potential importance of new experiments.", "date": "2002-04", "date_type": "published", "publication": "Physical Review C", "volume": "65", "number": "4", "publisher": "American Physical Society", "pagerange": "Art.
