Abstract: (Elsevier)
By calculating the two- and three-point functions at the one-loop level in weak-coupling lattice QCD we have found the numerical relation between the Λ parameter of the lattice theory and that of the continuum theory: Λ ( α =1 ) MOM = 83.5 Λ lattice for SU(3), Λ ( α =1 ) MOM = 57.5 Λ lattice for SU(2). This relation sets the scale for all lattice calculations in QCD.- QUANTUM CHROMODYNAMICS: PERTURBATION THEORY
