HADRON DEGENERATE MULTIPLET MASS SPECTRUM FROM QUARK-MONOPOLE EQUIVALENCE

Abstract

Non-observation of quarks or monopoles suggests their equivalence, as has been proposed within string and bag and other models and implied for QCD by the monopole solutions. The possible magnetic nature of quarks is investigated within a non-Abelian field theory with magnetic sources and fermions and color. The sources are shown to eliminate the non-analytic singularities of the field Aμ by a scale-setting mechanism which introduces a degenerate mass. The scale-setting mechanism follows from the requirement of gauge covariance by removal of the non-gauge covariant term which includes essential singulari-ties of [Formula: see text]. The low-lying hadron degenerate mass spectrum is obtained in terms of the degenerate mass and the colored symmetry.
