We perform a nonperturbative determination of the O(a)-improvement coefficient cSW and the critical hopping parameter kappac for Nf=3, 2, and 0 flavor QCD with the (RG) renormalization-group-improved gauge action using the Schrödinger functional method. In order to interpolate cSW and kappac as a function of the bare coupling, a wide range of beta from the weak coupling region to the moderately strong coupling points used in large-scale simulations is studied. Corrections at finite lattice size of O(a/L) turned out to be large for the RG-improved gauge action, and hence we make the determination at a size fixed in physical units using a modified improvement condition. This enables us to avoid O(a) scaling violations which would remain in physical observables if cSW determined for a fixed lattice size L/a is used in numerical simulations. |
