Abstract

The local composite operator Aμ2 is analysed within the algebraic renormalization in Yang-Mills theories in linear covariant gauges. We establish that it is multiplicatively renormalizable to all orders of perturbation theory. Its anomalous dimension is computed to two-loops in the MS scheme. © 2003 Published by Elsevier B.V.
