The Parity doublet model with fluctuations — •Johannes Weyrich1, Nils Strodthoff2, and Lorenz von Smekal1 — 1TU Darmstadt — 2Universität Heidelberg
In the 1970s the Walecka model and the chiral Walecka model were developed and have since been studied intensively. It was noted early on, however, that the chiral model leads to massless Lee-Wick nuclear matter in the chirally restored phase.
A promising variant to describe nuclear matter and chiral symmetry restoration consitently is the parity doublet model (or mirror model). It has already been treated in a mean field (MF) approach with promising results. This is motivation for us to to examine this model with functional renormalization group (FRG) methods, hence including full mesonic fluctuations.
