On the Eichten--Preskill Proposal for Lattice Chiral Gauge Theories

TL;DR

This paper evaluates the Eichten--Preskill proposal for lattice chiral gauge theories, finding it unlikely to succeed due to dynamical behaviors similar to previous unsuccessful approaches.

Contribution

The study provides a critical analysis of the Eichten--Preskill proposal using strong and weak coupling methods, demonstrating its limitations in producing chiral fermions.

Findings

The proposal is unlikely to work for lattice chiral gauge theories.

Dynamical behavior similar to the Smit--Swift proposal was observed.

Chiral fermions do not emerge from this approach.

Abstract

We have studied the Eichten--Preskill proposal for constructing lattice chiral gauge theories using both strong and weak coupling methods. The results indicate that this proposal is unlikely to work due to a dynamical behavior similar to that of the Smit--Swift proposal, which also does not give rise to chiral fermions.
