HIGH-TEMPERATURE LIMIT OF THERMAL QCD

We study the high-temperature behaviour of the n-point function to one-loop order in thermal QCD. We employ an analytic continuation of the imaginary-time formalism. The leading terms are all of order T2. They are totally symmetric in their Lorentz indices and traceless. They are gauge independent and obey simple, QED-like, Ward identities. The n-point functions for n>3 can be expressed as linear combinations with rational coefficients of the 2- and 3-point functions - a fact which follows from the symmetry, tracelessness and Ward identities. © 1990.
