We continue the study of a local, gauge invariant Yang-Mills actioncontaining a mass parameter, which we constructed in a previous paper startingfrom the nonlocal gauge invariant mass dimension two operator F_{\mu\nu}(D^2)^{-1} F_{\mu\nu}. We return briefly to the renormalizability of the model,which can be proven to all orders of perturbation theory by embedding it in amore general model with a larger symmetry content. We point out the existenceof a nilpotent BRST symmetry. Although our action contains extra(anti)commuting tensor fields and coupling constants, we prove that our modelin the limit of vanishing mass is equivalent with ordinary massless Yang-Millstheories. The full theory is renormalized explicitly at two loops in the MSbarscheme and all the renormalization group functions are presented. We end withsome comments on the potential relevance of this gauge model for the issue of adynamical gluon mass generation.
