A model for fermion mass generation in Technicolor theory

TL;DR

This paper proposes a model within the Technicolor framework where fermion masses are generated through couplings to scalar fields, enabling transitions between different technifermion chiral states.

Contribution

It introduces a novel mechanism for fermion mass generation in Technicolor models via scalar-fermion couplings that facilitate chiral transitions.

Findings

Fermions acquire masses through scalar-mediated transitions.

The model extends the Farhi-Susskind Technicolor framework.

Potential implications for Standard Model fermion mass hierarchies.

Abstract

We consider the $SU(N_{TC})$ Farhi - Susskind Technicolor model, in which SU(2) doublets of technifermions are right-handed while SU(2) singlets of technifermions are left-handed. We add coupling of fermions and technifermions to $SU(N_{TC})$ fundamental massive scalar fields. Due to this coupling the transitions between both types of fermions occur. Therefore the Standard Model fermions acquire masses.
