In-medium properties of vector and (pseudo-)scalar mesons — •Pascal Gunkel, Christian Fischer, and Philipp Isserstedt — Justus-Liebig Universität Gießen, 35392 Gießen, Deutschland

We report on recent results on the phase structure of strongly-interacting matter using the functional Dyson-Schwinger approach to QCD. We discuss results for masses, wave functions, and decay constants of (light) vector, scalar, and pseudoscalar mesons for finite chemical potentials up to the first-order phase transition. They are obtained from the corresponding homogeneous Bethe-Salpeter equations, coupled to a set of truncated Dyson-Schwinger equations for the quark and gluon propagators of Landau-gauge QCD. We confirm the Silver-Blaze property and extend previous calculations [1] to finite temperature.
