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

TL;DR

This paper introduces a novel approach to electroweak composite scalars based on a high-scale gauge interaction with an $SU(2)_L imes SU(2)_R imes SU(4)$ symmetry, leading to spontaneous SU(2) symmetry breaking.

Contribution

It develops a new framework for electroweak scalars from a fundamental gauge interaction with a specific high-scale group structure, highlighting spontaneous symmetry violation.

Findings

Constructed the topological electroweak vacuum filled by instantons.

Derived fermion mass equations showing spontaneous SU(2) flavor symmetry violation.

Indicated the possibility of large fermion mass ratios.

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.
