PNJL model analysis of the Roberge-Weiss transition endpoint at imaginary chemical potential

Abstract

Motivated by lattice QCD studies we investigate the RW transition endpoint at imaginary chemical potential in a two-flavor PNJL model. We focus on the quark-mass dependence of the endpoint using different forms of the Polyakov-loop potential.
