Spontaneous SU(2) symmetry violation in the $SU(2{)}_L\times SU(2{)}_R\times SU(4)$ electroweak model

Abstract

A new approach to EW composite scalars is developed, starting from the fundamental gauge interaction on high scale. The latter is assumed to have the group structure $SU(2{)}_L\times SU(2{)}_R\times SU(4)$ where SU(4) is the Pati-Salam color-lepton group. The topological EW vacuum filled by instantons is explicitly constructed and the resulting equations for fermion masses exhibit spontaneous SU(2) flavor symmetry violation with possibility of very large mass ratios.
