Abstract

We approach the non-perturbative regime in finite temperature QCD within a formulation in Polyakov gauge. The construction is based on a complete gauge fixing. Correlation functions are then computed from Wilsonian renormalisation group flows. First results for the confinement-deconfinement phase transition for SU(2) are presented. Within a simple approximation we obtain a second order phase transition within the Ising universality class. The critical temperature is computed as T_c = 305 MeV.
