Abstract

The Adler function D is found exactly in supersymmetric QCD. Our exact formula relates D(Q2) to the anomalous dimension of the matter superfields γ(αs(Q2)). 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.
