摘要：
The coefficient c(sw) appearing in the Sheikholeslami-Wohlert improved action is computed to 1-loop perturbation theory for improved gluon actions including six-link loops. The O(a) improvement coefficients for the dimension-3 isovector composite operators bilinear in the quark fields are also computed to 1-loop order of perturbation theory with degenerate non-vanishing quark masses.
