Dyson-Schwinger equations in dense matter studies

Abstract: The current state-of-the-art quark matter model in astrophysics is the thermodynamic bag model (tdBAG). This model approximates the effect of quark confinement, but does not explicitly account for the breaking of chiral symmetry which is an important property of Quantum Chromodynamics (QCD). The QCD theory has not yet been solved and therefore necessitates the use of such effective models and carries the risk of neglecting important properties of matter. The Dyson-Schwinger equation (DSE) formalism is a promising tool for dense matter studies. It allows to derive effective models directly from the QCD theory with a specific set of approximations. In my talk I will show an example of such models, their derivation and the impact on both the phase diagram and astrophysical observables.
