Low temperature relation for the trace of the energy-momentum tensor in QCD with light quarks

Abstract

It is shown that the temperature derivatives of the anomalous and normal (quark massive term) contributions to the trace of the energy-momentum tensor in QCD are equal to each other in the low temperature region. The physical consequences of this relation are discussed.
