Scale Factor in Double Parton Collisions and Parton Densities in Transverse Space
A. Del Fabbro, D. Treleani
Abstract
The scale factor σeff, 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 σeff 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.
