The QCD deconfinement transition for heavy quarks and all baryon chemical potentials I — •Jens Langelage — Max-von-Laue-Str. 1, 60438 Frankfurt am Main

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. 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 first part, we derive the effective lattice action and present details of the calculation.
