摘要：

We evaluate the ratio of the scale parameter Lambda in domain wall QCD to the one in continuum theory at the one-loop level incorporating the effect of massless quarks. We show that the Pauli-Villars regulator is required to subtract the unphysical massive fermion modes that emerge in the fermion loop contributions to the gluon self-energy. Detailed results are presented as a function of the domain wall height M.
