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

Abstract

The clover coefficient $\csw$ is computed at one loop order of 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 calculated.
