In this talk we extend the Polyakov-quark-meson model to Nf = 2+ 1 quark flavors and study its bulk thermodynamics at finite temperatures in mean-field approximation. Three different Polyakov-loop potentials are considered. Our findings are c onfronted to recent QCD lattice simulations of the RBC-Bielefeld and HotQCD collaborations. F urthermore, the finite chemical potential expansion of the quark-number susceptibility in a T aylor series around vanishing chemical potential is analyzed. By… CONTINUE READING
