Dependence of the Chiral Symmetry Restoration Transition on the Quark Self-Energy Kernel

Abstract

The dependence of the dressed quark propagator on the quark chemical potential is investigated in various models based on the Dyson-Schwinger equations. We find that the critical chemical potential of the chiral symmetry restoration transition is strongly dependent on the nature of the interaction kernel in the infrared region.
