Abstract

We use a χ2 minimization procedure to parameterize the Polyakov loop and (axial-)vector meson extended Nf = 2 + 1 flavor linear sigma model (LσM) based on tree-level decay widths and vacuum scalar and pseudoscalar curvature masses which includes the contribution of the constituent quarks. Using a quark improved Polyakov loop potential and a simple approximation for the grand potential, we determine and compare with lattice results the pressure and thermodynamical observables derived from it. We also determine the location of the critical end point of the μB-T phase diagram.
