Description

For a description of matter at high temperature and density effective
models of Nambu-Jona-Lasinio type have proven most useful. The Polyakov
loop extended NJL (PNJL) model can reproduce results of lattice QCD at
zero and imaginary chemical potential, where LQCD has no sign problem. In
the contribution we present the dependence of the first-order phase
transition line and its critical endpoint in the PNJL model phase diagram
when the following aspects are taken into account: the parametrization of
the effective potential U($\Phi, \bar{\Phi}$; T ); including of the quarks
repulsion (vector interaction);
an additional interaction between quarks and gluons.
