Two-loop anomalous dimensions for the structure function h1

arXiv:hep-ph/9706420 · doi:10.1103/PhysRevD.56.R2504

Abstract

Chiral-odd structure function h1 is expected to be measured in polarized Drell-Yan process. We calculate two-loop anomalous dimensions for h1 in the minimal subtraction scheme. Dimensional regularization and Feynman gauge are used for calculating the two-loop contributions. Our results are important in studying Q^2 dependence of h1.
