摘要：The 3-D Z(3) Potts model is a model for nite temperature QCD with heavy quarks. The chemical potential in QCD becomes an external magnetic eld in the Potts model. Following Alford et al.[3], we revisit this mapping, and determine the phase diagram for an arbitrary chemical potential, real or imaginary. Analytic continuation of the phase transition line between real and imaginary chemical potential can be tested with precision. Our results show that the chemical potential weakens the heavy-quark deconnement transition in QCD.
