On gamma_5 in higher-order QCD calculations and the NNLO evolution of the polarized valence distribution

S. Moch, J. A. M. Vermaseren, A. Vogt

We discuss the prescription for the Dirac matrix gamma_5 in dimensional regularization used in most second- and third-order QCD calculations of collider cross sections. We provide…
