Abstract

The contribution of Lorentz nonscalar operators to finite temperaturecorrelation functions is discussed. Using the local duality approach for the one-pion matrix element of a product of two vector currents, the temperature dependence of the average gluonic stress tensor is estimated in the chiral limit to be [E2 + B2]T = (pi2/10)bT4. At a normalization point mu = 0.5 GeV we obtain b almost-equal-to 1.1. Together with the known temperature dependence of the Lorentz scalar gluon condensate we are able to infer [E2]T and [B2]T separately in the low-temperature hadronic phase.
