Shocks and quark-meson scatterings at large density

TL;DR

This paper investigates the phase structure of the two-flavour quark-meson model at high density, incorporating advanced techniques to accurately determine the QCD phase boundary and the effects of shocks and fluctuations.

Contribution

It introduces a combined approach using the functional renormalisation group to include shocks and a self-consistent order parameter potential in the analysis of dense QCD matter.

Findings

Enhanced understanding of the QCD phase boundary at large density

Inclusion of shock formation and propagation effects

Quantitative insights into chiral symmetry breaking mechanisms

Abstract

We discuss the phase structure of the two-flavour quark-meson model including quantum, thermal, density and critical fluctuations with the functional renormalisation group. This study combines two technical advances in the literature, that are also chiefly important for the quantitative access of the phase boundary of QCD at large density or baryon chemical potential. Specifically we allow for the formation and propagation of shocks as well as a fully self-consistent computation of the order parameter potential for chiral symmetry breaking.
