QCD sum rules I: Perturbative results for current correlators

S.C. Generalis, Sotirios Generalis

    Research output: Contribution to journalArticlepeer-review


    New results are given to two-loop order and for quark masses of arbitrary flavour for the perturbative contribution to the coefficient function of the unit operator in the operator product expansion (OPE) of a vector correlator. A simple transformation of the presented results provides results for axial correlators.
