Universality-breaking effects in DIS and Drell-Yan

By Stephane Peigne

Abstract

6 pages, 1 figure, talk given at DIS 2003, St. Petersburg, 23-27 April 2003Several properties of high energy hadronic collisions are illustrated by comparing DIS and the Drell-Yan process within a scalar QED model. Diffraction and transverse momentum broadening within the target system are found to be non-universal. Here these effects are simply due to the Coulomb phase shift in the Drell-Yan production amplitude
