Studying properties of the QCD phase diagram with Dyson-Schwinger equations — Christian S. Fischer, Gernot Eichmann, Christian H. Lang, and •Christian A. Welzbacher — Institut für Theoretische Physik, Justus-Liebig-Universität Giessen, Heinrich-Buff-Ring 16, D-35392 Giessen, Germany
The Dyson-Schwinger equations (DSEs) as one kind of functional methods provides us with a toolbox to investigate the structure of the QCD phase diagram. By solving the carefully truncated coupled set of equations, the quark and gluon propagators at finite temperature and light-quark chemical potential are obtained. Those quantities give insights about the chiral and deconfinement phase transitions and have interesting analytic properties. We present results for Nf=2+1 flavors and discuss the location of a potential critical endpoint as well as the possible influence of baryonic degrees of freedom on its position.
