Higher covariant derivative regularization revisited

TL;DR

This paper reviews and defends the higher covariant derivative regularization method for gauge theories, addressing previous objections, proving its consistency, and developing a new approach for regularizing overlapping divergences.

Contribution

It provides a comprehensive review, resolves past criticisms, and introduces a novel technique for handling overlapping divergences in gauge theory regularization.

Findings

The method's consistency is proven.

Objections in literature are addressed.

A new approach to overlapping divergencies is developed.

Abstract

The method of higher covariant derivative regularization of gauge theories is reviewed. The objections raised in the literature last years are discussed and the consistency of the method is proven. New approach to regularization of overlapping divergencies is developped.
