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

High Energy Physics - Lattice 2009-10-31 v1

Abstract

The coefficient cswc_{\rm 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(aa) 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.
