Abstract

Deconfinement phase transition due to disappearance of confining colorelectric field correlators is described using nonperturbative equation of state. The resulting transition temperature $T_{c} (μ)$ at any chemical potential $μ$ is expressed in terms of the change of gluonic condensate $Δ G_{2}$ and absolute value of Polyakov loop $L_{f u n d} (T_{c})$ , known from lattice and analytic data, and is in good agreement with lattice data for $Δ G_{2} \approx 0.0035$ GeV $^{4}$ . E.g. $T_{c} (0) = 0.27; 0.19; 0.17$ GeV for $n_{f} = 0, 2, 3$ respectively.
