QCD pressure at two loops in the temporal gauge

We apply the method of zeta functions, together with the n ^∗_μ prescription for the temporal gauge, to evaluate the thermodynamic pressure in QCD at finite temperature T. Working in the imaginary-time formalism and employing a special version of the unified-gauge prescription, we show that the pure-gauge contribution to the pressure at two loops is given by P^gauge₂ = -( g²/144 N_cN_gT⁴, where N_candN_g denote the number of colours and gluons, respectively. This result agrees with the value in the Feynman gauge.
