Query: Phase diagram and thermodynamics of the PNJL model   QCD-based thermodynamics at zero and finite quark chemical potential is
studied using an extended Nambu and Jona-Lasinio approach in which quarks
couple simultaneously to the chiral condensate and to a background temporal
gauge field representing Polyakov loop dynamics. This so-called PNJL model thus
includes features of both deconfinement and chiral symmetry restoration. We
discuss the phase diagram as it emerges from this approach in close comparison
with results from lattice QCD thermodynamics. The critical point, separating
crossover from first order phase transition, is investigated with special focus
on its quark mass dependence, starting from the relatively large masses
presently accessible by lattice simulations, down to the chiral limit.
