Abstract
We have redone a recent two-loop computation of the critical mass for Wilso n fermions in lattice QCD by evaluating Feynman integrals with the coordina te-space method. We present the results for different types of infrared reg ularization. We confirm both the previous numerical estimates and the power of the coordinate-space method whenever high accuracy is needed.
