On the canonical quantization of anomalous SU(N) chiral Yang-Mills models

TL;DR

This paper investigates the canonical quantization of anomalous SU(N) chiral Yang-Mills models, demonstrating that gauge invariance can be preserved despite the degeneracy of the Wess-Zumino action.

Contribution

It introduces a method to maintain gauge invariance in the canonical quantization of anomalous models with degenerate Wess-Zumino actions.

Findings

Gauge invariance can be preserved in anomalous models

Degeneracy of the Wess-Zumino action does not necessarily break gauge invariance

Provides a framework for consistent quantization of anomalous gauge theories

Abstract

Canonical quantization of anomalous SU(N) Yang-Mills models is considered. It is shown that the gauge invariance of the quantum theory can be saved in spite of degeneracy of the Wess-Zumino action.
