Power corrections in eikonal cross sections

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

We discuss power corrections associated with the infrared behavior of the perturbative running coupling in the eikonal approximation to Drell-Yan and other annihilation cross sections in hadron-hadron scattering. General properties of the eikonal approximation imply that only even powers of the energy scale are necessary.
