摘要：
We have determined the non-perturbative O(a)-improvement coefficient c(SW), for four flavors of Wilson quarks with the plaquette gauge action in a range of beta >= 5.0. The data are fitted with several Pade approximation formulae to get an impression of the stability. A small extrapolation below beta = 5.0 seems acceptable. (C) 2009 Elsevier B.V.
