Quantum field theories out of thermal equilibrium. Pt. 2

The transport coefficients for quarkless QCD are estimated in the high and low temperature limits. The effect on the entropy production in the Bjorken model is examined. It is shown that in the gluon or high temperature phase the dissipative entropy is negligible. However in the glueball or low temperature phase, although the total entropy is smaller than in the gluon phase, the relative dissipative entropy can be large. (orig.)
