Abstract: (Elsevier)
We determine the transition points β c and plaquette energies E p of U(1), SU(2) and SO(3) lattice gauge theories in 4 and 5 dimensions by mean-field methods, and compare with corresponding values determined by the Monte Carlo technique. In every case, the mean-field and Monte Carlo values for β c and E p agree to within a few percent.- LATTICE FIELD THEORY
