Two-loop relation between the bare lattice coupling and the MSbar coupling in pure SU(N) gauge theories
Martin Luescher, Peter Weisz
Abstract
We report the result of a computation of the relation between the renormalized coupling in the MSbar scheme of dimensional regularization and the bare coupling in the standard lattice formulation of the SU(N) Yang-Mills theory to two-loop order of perturbation theory and discuss some of its implications.
