Perturbative determination of $c_{SW}$ for plaquette and Symanzik gauge action and stout link clover fermions

Abstract

Using plaquette and Symanzik improved gauge action and stout link clover fermions we determine the improvement coefficient $c_{SW}$ in one-loop lattice perturbation theory from the off-shell quark-quark-gluon three-point function. In addition, we compute the coefficients needed for the most general form of quark field improvement and present the one-loop result for the critical hopping parameter ${\kappa }_c$. We discuss mean field improvement for $c_{SW}$ and ${\kappa }_c$ and the choice of the mean field coupling for the actions we have considered.
