$U_L(2)\bigotimes U_R(2) $ Model of Electro-Weak Interaction

TL;DR

This paper develops a gauge model for electroweak interactions that generates all boson fields, including the Higgs, through symmetry breaking without requiring a scalar field, providing a novel perspective on Higgs boson origin.

Contribution

It introduces a $U_L(2) imes U_R(2)$ gauge model where Higgs fields arise from gauge symmetry breaking, differing from the Standard Model approach.

Findings

All boson fields, including Higgs, are generated by initial gauge fields.

A broad spectrum of Higgs boson states is identified.

Masses of Higgs particles in these states are calculated.

Abstract

The $U_L(2)\bigotimes U_R(2) $ gauge model for the unified theory of the electromagnetic and weak interactions which is free from a prior self-interaction scalar field, is developed. Due to breaking the initial symmetry the $SU_L(2)\bigotimes U_R(1) $ Lagrangian is derived. The obtained $SU_L(2)\bigotimes U_R(1) $ Lagrangian contains the whole of terms corresponding both to free boson and fermion fields and to interaction between them, as it takes place in the Standard Model (SM) . We show that all boson fields, including the Higgs one, directly arise due to breaking the initial symmetry, and are generated by the initial gauge fields in contrary to the Standard Model consideration. The Higgs fields are studied in detail. A broad spectrum of states of the Higgs bosons is found. The masses of the Higgs particle in such states are calculated.
