Two-loop renormalization of Wilson loop for Drell-Yan production
A. V. Belitsky
Abstract
We study the renormalization of the Wilson loop with a path corresponding to the Drell-Yan lepton pair production in two-loop approximation of perturbation theory. We establish the renormalization group equation in next-to-leading order and find a process specific anomalous dimension GammaDY in the corresponding approximation.
