Abstract
The non-perturbative determined by the Schrödinger 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 with a constant L are reported.
