Gauge invariant mean field technique for lattice gauge theories with scalar matter
Abstract
Any lattice gauge theory with scalar matter can be written in terms of gauge invariant fields with constraints on plaquettes and cubes of the lattice. We develop a mean field approximation in the new variables. The method is applied to the Z(2) and Z(4) Higgs models in four dimensions with encouraging results.
