Abstract
We compute the effect of small-size instanton corrections to current-current correlators, for all combinations of axial, vector, and possibly flavour non-diagonal currents. We apply our result to the hadronic decays of the lepton, in order to assess the reliability of the determination of from the hadronic width.
