Taylor coefficients of the quark pressure from Dyson-Schwinger equations — •Philipp Isserstedt¹, Michael Buballa², and Christian Fischer¹ — ¹Institut für Theoretische Physik, Justus-Liebig-Universität Gießen — ²Institut für Kernphysik, Theoriezentrum, Technische Universität Darmstadt

We report on an investigation of the Taylor coefficients of the quark pressure using the non-perturbative framework of Dyson-Schwinger equations. The rainbow-ladder truncation is used to get a closed system of equations for the quark propagator and the derivatives of the latter with respect to the chemical potential are calculated self-consistently instead of using a difference quotient. We compare our results for the second and fourth coefficient to a previous Dyson-Schwinger study and results from lattice QCD.
