Vp. Nair, HAMILTONIAN ANALYSIS OF THE EFFECTIVE ACTION FOR HARD THERMAL LOOPS IN QCD, Physical review. D. Particles and fields, 50(6), 1994, pp. 4201-4208
The effective action for hard thermal loops in quantum chromodynamics
(QCD) is related to a gauged Wess-Zumino-Novikov-Witten theory. Some o
f the technical issues of this approach are clarified and the Hamilton
ian formulation is presented. The two-point correlator for the induced
current in QCD is obtained; some simplifications of the dynamics of t
he longitudinal modes are also pointed out.
