Non-perturbative evaluation of cSW for smeared link clover fermion and Iwasaki gauge action

Abstract

We performed a rough estimate of the non-perturbative value of the clover term coefficient cSW for the APE stout link Wilson fermion. We varied the number of smearings from Nsmear = 1 to 6 and adopted b values roughly corresponding to the lattice spacing of 0:1 fm. We used the Schrödinger functional technique for an evaluation of cSW and found that cSW decreases monotonically as we increase Nsmear but has a 10% order of deviation from the tree level value for Nsmear = 6.
