Effective actions for finite temperature Lattice Gauge Theories.
Abstract
We consider a lattice gauge theory at finite temperature in ( d + 1) dimensions with the Wilson action and different couplings β_{t} and β_{s} for timelike and spacelike plaquettes. By using the character expansion and SchwingerDyson type equations we construct, order by order in β_{s}, an effective action for the Polyakov loops which is exact to all orders in β_{t}. As an example we construct the first nontrivial order in β_{s} for the (3+1) dimensional SU(2) model and use this effective action to extract the deconfinement temperature of the model.
