The three-loop β-function of SU(N) lattice gauge theories with Wilson fermions
(1998)
We calculate the third coefficient of the lattice β-function associated with the Wilson formulation for both gauge fields and fermions. This allows us to evaluate the three-loop correction (linear in g2 0) to the relation ...
The two-loop relation between the bare lattice coupling and the MS coupling in QCD with Wilson fermions
(1998)
We calculate the two-loop relation between the coupling renormalized in the MS̄ scheme and the bare lattice coupling g0 in QCD with Wilson fermions, extending the pure gauge results of Lüscher and Weisz. Our calculation ...
