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 $T_c(\mu )$ at any chemical potential $\mu$ is expressed in terms of the change of gluonic condensate $\Delta G_2$ and absolute value of Polyakov loop $L_{fund}(T_c)$, known from lattice and analytic data, and is in good agreement with lattice data for $\Delta G_2\approx 0.0035$ GeV${}^4$. E.g. $T_c(0)=0.27;0.19;0.17$ GeV for $n_f=0,2,3$ respectively.
