Dynamical fermion mass generation by strong gauge interaction shielded by a scalar field

TL;DR

This paper explores a model where strong gauge interactions and scalar fields lead to dynamical fermion mass generation, potentially offering an alternative to the Higgs mechanism by producing heavy fermions as bound states.

Contribution

It introduces a lattice gauge model with scalar and fermion matter fields that dynamically breaks chiral symmetry, proposing a new mechanism for fermion mass generation beyond the standard model.

Findings

Heavy fermions can form as neutral bound states of fermions and scalars.

The mechanism provides an alternative to the Higgs for mass generation.

Models suggest a new strong force could produce observable heavy fermions.

Abstract

The strongly coupled lattice gauge models with confined fermion and scalar matter fields, which in a certain phase break dynamically a global chiral symmetry, are reconsidered from the point of view of the existence of heavy fermions. If these models are interpreted as describing a new strong force beyond the standard model, such heavy fermions can arise as neutral bound states of the fundamental fermion and scalar. The discussed mechanism could be considered as an alternative to the Higgs mechanism.
