Electromagnetic Spectral Functions from the FRG — •Christopher Jung1, Naoto Tanji2, Ralf-Arno Tripolt2, Lorenz von Smekal1, and Jochen Wambach2 — 1JLU, Giessen — 2ECT*, Trento
We present first results on electromagnetic spectral functions as obtained by applying the non-perturbative functional renormalization group approach to an effective low-energy theory motivated by the gauged linear sigma model. We study the in-medium behavior of these spectral functions in different regimes of the phase diagram and aim in calculating temperature and chemical potential dependent dilepton rates. In particular, we focus on possible signatures in these data for a critical endpoint (CEP) and the restoration of chiral symmetry.
