Abstract

We compute the O(1/Nf2) corrections to the flavour non-singlet quark bilinear currents in QCD in arbitrary spacetime dimensions. Hence, the anomalous dimension of the QED current ψ̄ σμnu;ψ is deduced at four loops in the MS scheme up to one unknown parameter. © 2001 Elsevier Science B.V. All rights reserved.
