A test for the temporal axial gauge at finite temperature: The two-loop gluon-interaction pressure calculated in the real time formalism

  • Published:

Abstract

Using the 2×2 matrix propagator previously found by the author, we calculate the interaction pressure of the gluon plasma to two loops at high temperature using the temporal axial gauge in the real time formalism. This quantity is gauge invariant and is thus a good check for the validity of the Feynman rules found for the temporal gauge at finite temperature. Our result is identical to that found by Landsman et al. and Kapusta using covariant gauges in the real and imaginary time formalisms respectively.
