摘要：

We relate quark confinement, as measured by the Polyakov-loop, order parameter, to colour confinement, as described by the Kugo-Ojima/Gribov-Zwanziger scenario. We identify a simple criterion for quark confinement based on the IR behaviour of ghost and gluon propagators, and Compute the order-parameter potential from the knowledge of Landau-gauge correlation functions with the aid of the functional RG. Our approach predicts the deconfinement transition in quenched QCD to be of first order for SU(3) and second order for SU(2) - in agreement with general expectations. As an estimate for the critical temperature, we obtain T-c similar or equal to 284 MeV for SU(3). (C) 2010 Elsevier B.V. All rights reserved.
