Power corrections in eikonal cross sections
Eric Laenen🇳🇱 · George Sterman🇺🇸 · Werner Vogelsang🇺🇸
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.
