", "abstract": "A new model of the higher symmetry of elementary particles is introduced ln which the eight known baryons are treated as a supermultiplet, degenerate in the limit of unitary symmetry but split into isotopic spin multiplets by a symmetry-breaking term. The symmetry violation is sscribed phenomenologically to the mass differences. The baryons correspond to an eight-dimensional irreducible representation of the unitary group. The pion and K meson fit into a similar set of eight particles along with a predicted pseudoscalar meson X/sup o/ having I = 0. A ninth vector meson coupled to the baryon current can be accomodated natarally in the scheme. It is predicted that the eight baryons should all have the same spin and parity and that pseudoscalar and vector mesons should form octets with possible additional singlets. The mathematics of the unitary group is described by considering three fictitious leptons, nu , e/sup -/ , and mu /sup -/, which may throw light on the structure of weak interactions. (D.

In principle, these measurements would enable one to determine the magnet positions (to within an overall translation and/or rotation) much more simply than by conventional techniques. Furthermore,\nthe procedure of measurement and adjustment could be carried out completely automatically, if desired. \n\nThe principle difficulty with the method lies in the accumulation of errors from the large number of observations.

", "abstract": "The possibility of generalizing the Yang-Mills trick is examined. Thus we seek theories of vector bosons invariant under continuous groups of coordinate-dependent linear transformations. All such theories may be expressed as superpositions of certain \"simple\" theories; we show that each \"simple\" theory is associated with a simple Lie algebra. We may introduce mass terms for the vector bosons at the price of destroying the gauge-invariance for coordinate-dependent gauge functions.\nThe theories corresponding to three particular simple Lie algebras \u2014 those which admit precisely two commuting quantum num- bers \u2014 are examined in some detail as examples. One of them might play a role in the physics of the strong interactions if there is an underlying super-symmetry, transcending charge independence, that is badly broken.\nThe intermediate vector boson theory of weak interactions is discussed also. The so-called \"schizon\" model cannot be made to conform to the requirements of partial gauge-invariance. It is possible, however, to find a formal theory of four intermediate bosons that are partially gauge-invariant and gives an approximate |\u0394I| = 1/2 rule.", "date": "2017-02-28", "date_type": "published", "publisher": "California Institute of Technology", "id_number": "CaltechAUTHORS:20170210-102604161", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20170210-102604161", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Atomic Energy Commission" }, { "agency": "Alfred P.

A misplaced magnet tends to deflect the orbit of the beam of protons and a series of errors in the placement of the magnets can very well deflect the beam out of the vacuum tube aperture.

The question is whether it is indeed possible to achieve and maintain the same tolerances for a machine that is 1.6 miles in diameter.
