The Quark-Meson Plasma in the Polyakov-loop-extended Nambu-Jona-Lasinio model

We will investigate the thermodynamics of a non-ideal quark plasma with correlations in the pion and sigma-meson interaction channels within the low-energy effective theory of quantum chromodynamics, i.e., the two-flavor Polyakov-loop-extended Nambu-Jona-Lasinio model. Using the path-integral representation of the thermodynamic potential we will study the behavior of the quark matter at finite temperature and density, in particular the contribution from constituent quarks as well as the collective nature of mesons and their dissociation due to the Mott effect.
