The QCD deconfinement transition for heavy quarks and all baryon chemical potentials II — •Stefano Lottini — ITP Goethe Universität, Frankfurt am Main, Deutschland

Using combined strong coupling and hopping parameter expansions, we derive an effective three-dimensional theory from thermal lattice QCD with heavy Wilson quarks. The theory depends on traced Polyakov loops only and correctly reflects the centre symmetry of the pure gauge sector as well as its breaking by finite mass quarks. It is valid up to certain orders in the lattice gauge coupling and hopping parameter, which can be systematically improved. As an application, we determine the deconfinement transition and its critical end point as a function of quark mass and all chemical potentials. In this part we discuss the numerical analysis of the model and draw the conclusions.
