Determination of c_sw in N_f=3+1 Lattice QCD with massive Wilson fermions
arXiv:1501.06753
Abstract
We develop a strategy for the non-perturbative determination of the O(a)-improvement coefficient c_sw for Wilson fermions with massive sea quarks. The improvement condition is defined via the PCAC relation in the Schrödinger functional. It is imposed along a line of constant physics designed to be close to the correct mass of the charm quark. The numerical work uses the tree-level improved Lüscher-Weisz gauge action in N_f=3+1 Lattice QCD.
