Computation of the improvement coefficient $c_{\mathrm{sw}}$ to 1-loop with improved gluon actions

Abstract

The coefficient $c_{\mathrm{sw}}$ appearing in the Sheikholeslami-Wohlert improved action is computed to one loop perturbation theory for improved gluon actions including six-link loops. The O($a$) improvement coefficients for the dimension three isovector composite operators bilinear in the quark fields are also computed to one loop order of perturbation theory with degenerate non-vanishing quark masses.
