NSPT calculations in the Schrodinger Functional formalism
arXiv:0910.4138
Abstract
Within the framework of the Schrödinger Functional (SF), we outline how to combine Numerical Stochastic Perturbation Theory (NSPT) and PCAC relations to determine the two-loop contributions to the improvement coefficients $c_A$ and $c_{SW}$ for Sheikholeslami-Wohlert-Wilson fermions.
