title: Exact adler function in supersymmetric QCD.
abstract: The Adler function D is found exactly in supersymmetric QCD. Our exact formula relates D(Q(2)) to the anomalous dimension of the matter superfields γ(α(s)(Q(2))). En route we prove another theorem: the absence of the so-called singlet contribution to D. While such singlet contributions are present in individual supergraphs, they cancel in the sum.
