Lambda-parameter of lattice QCD with the overlap-Dirac operator
Abstract
We compute the ratio L/MS between the scale parameter L, associated with a lattice formulation of QCD using the overlap-Dirac operator, and MS of the MS renormalization scheme. To this end, the necessary one-loop relation between the lattice coupling g0 and the coupling renormalized in the MS scheme is calculated, using the lattice background field technique.
