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.
