摘要：The running coupling of the Wilson fermon(JLQCD/CP-PACS) and that of Kogut-Susskind(KS)
fermion(MILC) are measured in the lattice Landau gauge QCD in
MOM scheme. The quark
propagator of the KS fermion is also measured and we find that it is infrared vanishing, which
implies that quarks are confined. The renormalization factor of the running coupling and the
tadpole renormalization define the scale of the quark wave function. Effects of the A2μ
condensates
of a few GeV2 are observed in the running coupling and also in the quark propagator.
