摘要：We describe the gluon plasma in zeroth order as a gas of free quasi-particles with a temperatureindependent dispersion relation of Gribov type, E(k)=qk2 + M4 k2 , that results fromthe restriction of the physical state space to the Gribov region. The effective mass M2 k controls infrared divergences of finite-temperature perturbation theory. The equation of state of this gas is calculated and compared with numerical lattice data. At high temperature T there are power corrections to the Stefan-Boltzmann law that are of relative order 1/T3 for pressure and 1/T4 for energy.
