Abstract

Using plaquette and Symanzik improved gauge action and stout link clover fermions we determine the improvement coefficient cSW 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 κc. We discuss mean field improvement for cSW and κc and the choice of the mean field coupling for the actions we have considered
