Abstract

A non-perturbative method of Field Correlators is applied to calculate the Polyakov loop dependence on temperature, L(T), in the 2+1 flavor QCD with small quark masses, so the only relevant scale is the color-electric string tension σ(T). Polyakov loop in the temperature range 100 MeV \lesssim T\lesssim 400 MeV is expressed via the heavy-light meson mass that decreases with T as √(σ(T)). The latter is deduced from a gradually vanishing chiral condensate. The resulting L(T) is in good agreement with recent lattice data.
