IoffeInstitute of Theoretical and Experimental Physics, Moscow 117259, RussiaAbstractCurrent correlators in QCD at a finite temperature T are considered from the viewpointof operator product expansion. It is stressed that at low T the heat bath must be representedby hadronic, and not quark-gluon states. A possibility to express the results in terms of T-dependent resonance masses is discussed. It is demonstrated that in order T
