RG analysis of the quark-meson model at finite temperature and density — •Bernd-Jochen Schaefer and Jochen Wambach — IKP, Schlossgartenstrasse 9,D-64289 Darmstadt

Renormalization group equations obtained by means of a proper-time regulator are used in order to analyze the chiral symmetry restoration at finite temperature and density in the two flavor quark-meson model. Results for the N_f = 2 QCD phase diagram are presented and compared with those coming from lattice simulations.
