Elastic and quasi-elastic $pp$ and $γ^{⋆} p$ scattering in the Dipole Model

Abstract

We have in earlier papers presented an extension of Mueller's dipole cascade model, which includes sub-leading effects from energy conservation and running coupling as well as colour suppressed saturation effects from pomeron loops via a ``dipole swing''. The model was applied to describe the total and diffractive cross sections in $pp$ and $γ^{*} p$ collisions, and also the elastic cross section in $pp$ scattering. In this paper we extend the model to describe the corresponding quasi-elastic cross sections in $γ^{*} p$ , namely the exclusive production of vector mesons and deeply virtual compton scattering. Also for these reactions we find a good agrement with measured cross sections. In addition we obtain a reasonable description of the $t$ -dependence of the elastic $pp$ and quasi-elastic $γ^{⋆} p$ cross sections.
