Title: Mean field with corrections in lattice gauge theory
Abstract: A systematic expansion of the path integral for lattice gauge theory is performed around the mean field solution. In this letter we present the results for the pure gauge groups Z(2), SU(2) and SO(3). The agreement with Monte Carlo calculations is excellent. For the discrete group the calculation is performed with and without gauge fixing, whereas for the continuous groups gauge fixing is mandatory. In the case of SU(2) the absence of a phase transition is correctly signalled by mean field theory.
