$SU(n)\otimes U(1{)}_c$ gauge models with spontaneous symmetry breaking

Abstract

A possible generalization of the technique of the standard model to $SU(n)\otimes U(1)$ gauge models is proposed. A special Higgs mechanism and a new kind of Yukawa couplings in unitary gauge are introduced. These allow us to obtain a general method of deriving boson mass spectrum and coupling coefficients which will be used to find an exact solution of the Pisano-Pleitez three-generation $SU(3)\otimes U(1)$ model. A new anomaly-free one-generation model is briefly discussed.
