Description

We consider simple modifications of the conventional Wilson action for lattice gauge theory. An SU(2) action is defined on plaquettes of 2 x 1 links. It is found to possess phase transitions in three- and four-dimensional realisations of the model. A similar model with gauge group Z(2) is also studied, and found to have two phases in three and four dimensions. We discuss the phase structure of Z(N) gauge models in four dimensions with several coupling constants and present phase diagrams for Z(4), Z(5) and Z(6). (orig.)
