The Lattice Λ Parameter in Domain Wall QCD
Aoki, Sinya · Kuramashi, Yoshinobu
Original · EN
We evaluate the ratio of the scale parameter Λ in domain wall QCD to the one in the continuum theory at 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 which emerge in the fermion loop contributions to the gluon self energy. Detailed results are presented as a function of the domain wall height M.
