Effective Polyakov loop models for QCD-like theories at finite baryon density — •Philipp Scior1, Lorenz von Smekal2 und Bjoern Wellegehausen2 — 1Institut für Kernphysik, Technische Universität Darmstadt — 2Institut für Theoretische Physik, Justus-Liebig-Universität Gießen
We study the heavy quark limit of QCD-like theories by using a three-dimensional Polyakov theory. This theory can be derived from the full QCD-like theory by a combined strong coupling expansion. In particular we investigate the cold and dense regime of the phase diagram where we expect to find the Silverblaze property realized as Bose-Einstein-condensation of diquarks or a fist order liquid-gas transition, depending on the gauge group of the theory. We find evidence for the Silverblaze property when the quark chemical potential μ reaches half the diquark mass. For even higher μ we find the deconfinement transition indicated by the rise of the Polyakov loop as well as the quark number density.
