Title:Rho parameters from odd and even chirality, thermal QCD sum rules

Abstract: Like the even chirality correlation functions of, say, the two vector currents, one can also consider odd chirality correlation functions to write thermal QCD sum rules. They contain fewer non-perturbative corrections, at least 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 rules are taken together to evaluate the effective parameters of the $\rho$ meson to second order in temperature. To within errors, the results are consistent and reproduce the absence of shift in the $\rho$ meson mass to this order.
