摘要

We study the temperature dependence of the adjoint Polyakov loop and its implication for the momentum spectrum of gluons in the mean-field approximation. This allows us to calculate the contribution of the thermal (transverse) gluons to the thermodynamic pressure. As an application, we evaluate the rates for the strange quark pair-production processes q (q) over bar -> s (s) over bar and gg -> s (s) over bar as functions of temperature including thermal effects on quark deconfinement and chiral symmetry breaking.
