Scale Factor in Double Parton Collisions and Parton Densities in Transverse Space

arXiv:hep-ph/0005273 · doi:10.1103/PhysRevD.63.057901

Abstract

The scale factor , which characterizes double parton collisions in high energy hadron interactions, is a direct manifestation of the distribution of the interacting partons in transverse space, in such a way that different distributions give rise to different values of in different double parton collision processes. We work out the value of the scale factor in a few reactions of interest, in a correlated model of the multi-parton density of the proton recently proposed.
