✦ Synopsis

We have determined non-perturbative values of the O(a) improvement coefficient csw in three-flavor dynamical QCD for the RG improved as well as the plaquette gauge actions, using the SchrGdinger functional scheme. Results are compared with l-loop estimates at weak gauge coupling. 0 non-perturbative 0 1 -loop ?

The non-perturbative csw determined by the Schrtidinger 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
