Symanzik improvement of lattice QCD with four flavors of Wilson quarks
arXiv:0911.4043 · doi:10.1016/j.physletb.2009.11.055
Abstract
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. The data are fitted with several Pade approximation formulae to get an impression of the stability. A small extrapolation below beta=5 seems acceptable.
