Chiral and deconfinement transitions in QCD with 2 and 2+1 flavours — Christian S. Fischer1,2 and •Jan Luecker1 — 1Institut für Theoretische Physik, Justus-Liebig-Universität Gießen, Heinrich-Buff-Ring 16, D-35392 Gießen, Germany — 2GSI Helmholtzzentrum für Schwerionenforschung GmbH, Planckstr. 1 D-64291 Darmstadt, Germany.
We investigate quantum chromodynamics at finite temperature and chemical potential by solving the truncated Dyson-Schwinger equations for the quark and gluon propagator. In this setup we study chiral and deconfinement transitions, from which the critical endpoint and the existence of a quarkyonic phase can be determined. Since we explicitly take unquenching effects in the gluon into account, we are able to include strange quarks and to study the gluon propagator in vicinity of the phase transition.
