Chiral Mirror-Baryon-Meson Model and Nuclear Matter beyond Mean-Field — •Johannes Weyrich^1,2, Nils Strodthoff³, and Lorenz von Smekal² — ¹TU Darmstadt — ²Justus-Liebig-Universität Gießen — ³Universität Heidelberg

We consider a chiral mirror-baryon-meson model to describe the properties of nuclear matter around the liquid-gas transition in the low temperature region of the QCD phase diagram together with chiral symmetry restoration in the high density phase. In the mean-field approximation this model is known to provide a successful description of nuclear matter properties. Here, we go beyond the mean-field approximation using a functional renormalization group (FRG) framework to study this chiral mirror-baryon-meson model (or parity doublet model) at finite temperature and baryon chemical potential.
