Power corrections to the differential Drell-Yan cross section
Abstract
We estimate the power corrections (infrared renormalon contributions) to the coefficient functions for the differential Drell-Yan cross-section d2σ/dQ2dy, where Q2 is the mass squared and y the rapidity of the produced lepton pair. We employ the dispersive method based on the analysis of one-loop Feynman graphs containing a massive gluon.
