${\gamma }_5$ in Dimensional Regularization: a Novel Approach

Abstract

A new Dimensional Regularization of ${\gamma }_5$ is proposed. Cyclicity and Lorentz covariance are enforced. The extension to generic dimension is based on the integral representation of the trace of gamma's, presented in a previous paper.

Comments: 36 pages, no figures. The second part of the paper, concerning a generic dimension D, has been written ex-novo with new results, new examples and in a user-friendly notation
