Vacuum Phase Transition at Nonzero Baryon Density

It is argued that the dominant contribution to the interaction of quark gluon plasma at moderate T ≥ T c is given by the nonperturba-tive vacuum field correlators. Basing on that nonperturbative equation of state of quark-gluon plasma is computed and in the lowest approximation expressed in terms of absolute values of Polyakov lines for quarks and gluons L f und (T); L adj (T) = (L f und) 9/4 known from lattice and analytic calculations. Phase transition at any µ is described as a transition due to vanishing of one of correlators, D E (x), which implies the change of gluonic condensate ∆G 2. Resulting transition temperature T c (µ) is calculated in terms of ∆G 2 and L f und (T c). The phase curve T c (µ) is in good agreement with lattice data.
