Remarks on a class of renormalizable interpolating gauges

TL;DR

This paper introduces a class of covariant gauges that interpolate between several well-known gauges, proves their renormalizability, and explicitly calculates their one-loop anomalous dimensions.

Contribution

It presents a new class of interpolating gauges with proven all-order renormalizability and explicit one-loop anomalous dimensions calculations.

Findings

The gauges interpolate between Landau, maximal Abelian, linear covariant, and Curci-Ferrari gauges.

Multiplicative renormalizability is established to all orders.

One-loop anomalous dimensions are explicitly computed in the MSbar scheme.

Abstract

A class of covariant gauges allowing one to interpolate between the Landau, the maximal Abelian, the linear covariant and the Curci-Ferrari gauges is discussed. Multiplicative renormalizability is proven to all orders by means of algebraic renormalization. All one-loop anomalous dimensions of the fields and gauge parameters are explicitly evaluated in the MSbar scheme.
