Total cross sections and event properties from real to virtual photons

Friberg, Christer LU and Sjöstrand, Torbjörn LU orcid (2000) In Journal of High Energy Physics 4(9 PART A).
Abstract

A model for total cross sections with virtual photons is presented. In particular γ*p and γ*γ* cross sections are considered. Our approach extends on a model for photoproduction, where the total cross section is subdivided into three distinct event classes: direct, VMD and anomalous. With increasing photon virtuality, the latter two decrease in importance. Instead Deep Inelastic Scattering dominates, with the direct class being the script O sign(αs) correction thereof. Hence, the model provides a smooth transition between the two regions. By the breakdown into different event classes, one may aim for a complete picture of all event properties.
