/ Abstract
Abstract The non-perturbative cSW determined by the Schrodinger functional (SF) method with the RG-improved gauge action in dynamical Nf = 3 QCD shows a finite volume effect when the numerical simulations are carried out at a constant lattice size L a . We remove the unwanted finite volume effect by keeping physical lattice extent L at a constant. The details of the method and the result obtained for non-perturbative cSW with a constant L are reported.
