摘要：
We investigate the finite temperature one loop renormalization of the pure QCD coupling constant in the real time formalism. The temperature dependence of the β function is derived in a generalized momentum space subtraction scheme. Due to the occurrence of multiple Bose-Einstein distribution functions, we find g2 (T) ≈ T-3 for asymptotic temperatures at fixed momentum subtraction scale. © 1990.
