Abstract: In this paper, we investigate operator product expansion for thermalcorrelation function of the two scalar currents. Due to breakdown of Lorentzinvariance at finite temperature, more operators of the same dimension appearin the operator product expansion than at zero temperature. We calculatedWilson coefficients in the short distance expansion and obtain operator productexpansion for thermal correlation function in terms of quark condensate, gluoncondensate, quark energy density and gluon energy density.
