Polyakov-Quark-Meson-Diquark Model for two-color QCD

Understand

We present an update on the phase diagram of two-color QCD from a chiral effective model approach based on a quark-meson-diquark model using the Functional Renormalization Group (FRG).

• We discuss the impact of perturbative UV contributions, the inclusion of gauge field dynamics via a phenomenological Polyakov loop potential, and the impact of matter backcoupling on the gauge sector.
• The corresponding phase diagram including these effects is found to be in qualitative agreement with recent lattice investigations.
