Deconfinement transition for nonzero baryon density in the Field Correlator Method
Abstract
Deconfinement phase transition due to disappearance of confining colorelectric field correlators is described using nonperturbative equation of state. The resulting transition temperature Tc(μ) at any chemical potential μ is expressed in terms of the change of gluonic condensate G2 and absolute value of Polyakov loop Lfund (Tc), known from lattice and analytic data, and is in good agreement with lattice data for G2 ≈ 0.0035 GeV4. E.g. Tc(0) =0.27; 0.19; 0.17 GeV for nf=0,2,3 respectively.
