Abstract

We apply the method of \underline{zeta} functions, together with the nμn_\mu^*-prescription for the temporal gauge, to evaluate the thermodynamic pressure in QCD at finite temperature TT. 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 P2\mboxgauge=(g2/144)NcNgT4P_2^{\mbox{{\scriptsize gauge}}} = -(g^2/144)N_cN_gT^4, where NcN_c and NgN_g denote the number of colours and gluons, respectively. This result agrees with the value in the Feynman gauge.
