Quarks and pions at finite chemical potential — •Pascal Gunkel and Christian S. Fischer — Institut für Theoretische Physik, Justus-Liebig Universität Gießen

We report on recent results on the the phase structure of strongly interacting matter, using the functional Dyson-Schwinger approach of QCD. Building upon previous works [1], we use different truncation schemes and explore their effects on the properties of the quark propagator and the resulting (pseudo-)scalar mesons at finite chemical potential. We discuss results for the masses, wave functions and decay constants below and above the first order transition at T=0 and study the validity of the Silver Blaze property.
