Rho parameters from odd and even chirality, thermal QCD sum rules - art. no. 116007

Like the even chirality correlation functions of, say, the two vector curre nts, one can also consider odd chirality correlation functions to write the rmal QCD sum rules. They contain fewer non-perturbative corrections, at lea st to the leading order. Here we write such a sum rule for the correlation function of vector and tensor "currents." The odd and even chirality sum ru les are taken together to evaluate the effective parameters of the rho meso n to second order in temperature.
