The phase diagram of the three-flavor quark-meson model — Bernd-Jochen Schaefer1, •Mathias Wagner2, and Jochen Wambach2,3 — 1Institut für Physik, Karl-Franzens-Universität, A-8010 Graz, Austria — 2Institut für Kernphysik, TU Darmstadt, D-64289 Darmstadt,Germany — 3Gesellschaft für Schwerionenforschung GSI, D-64291Darmstadt,Germany
In this talk we present first results of our calculation of the chiral phase diagram of three flavor quark-meson model. The dependence of the phase boundaries on the quark masses is discussed. The results for the in-medium masses of the mesons, the pressue, the quark-number density and chiral susceptibility are compared with other model and lattice calculations. These studies are the basis for a more sophisticated treatment within a functional renormalization group approach.
