Tuning improved anisotropic actions in lattice perturbation theory

Abstract

We discuss the tuning of the anisotropic clover action and Symanzik-improved gauge action in lattice perturbation theory. The fermion action is constructed from stout-smeared spatial links, which complicates the calculation considerably. In addition, the full quark-mass dependence of the action parameters is included in this study. We present results for the fermion and gauge aspect ratios for varying bare aspect ratios, quark masses and smearing parameters.
