Abstract

We computed the static potential and Wilson loops to O(alpha(2)) in perturbation theory for different lattice quark and gluon actions. In general, we find short distance lattice data to be well described by "boosted perturbation theory". For Wilson-type fermions at present-day quark masses and lattice spacings agreement within 10 % between measured "beta-shifts" and those predicted by perturbation theory is found. We comment on prospects for a determination of the real world QCD running coupling.
