Abstract

In the context of QCD sum-rules, hadronic properties are related to QCD correlation functions of composite operators. These QCD correlation functions are evaluated using an operator product expansion, where the non-perturbative values multiplied by perturbatively-calculated Wilson coefficients. We present here an updated calculation of the Wilson coefficient of the mixed QCD condensate calculated in d-dimensions, up to $O(m^3)$ in quark mass.
