Manifestly Gauge Invariant Models of Chiral Lattice Fermions

TL;DR

This paper introduces a gauge invariant lattice action for chiral models that avoids fermion doubling and aligns with continuum theory, advancing lattice gauge theory methods.

Contribution

It proposes a new lattice action for chiral fermions that maintains gauge invariance and eliminates fermion doublers in the continuum limit.

Findings

Lattice action is manifestly gauge invariant.

Fermion doublers are removed in the continuum limit.

The model accurately reproduces continuum chiral theories.

Abstract

A manifestly gauge invariant lattice action for nonanomalous chiral models is proposed which leads in the continuum limit to the theory free of doublers.
