Deep inelastic electron-proton scattering

Peterson, C. LU ; Walsh, T. F. and Zerwas, P. M. (1980) In Nuclear Physics B 174(2-3). p.424-444
Abstract

We study deep inelastic scattering of an electron or positron on an almost real photon target in the reaction e+e− → e+e− + hadrons with C = +, where one e+ or e− is scattered at small or zero angle, yielding a virtual photon γ(k), k2 ∼ O(−me2). The other e− or e+ scatters on this virtual photon, emerging at large angle. We emphasize particularly: (i) the pointlike QCD contribution to the structure functions of the photon; (ii) the measurability of the structure functions under realistic experimental conditions; (iii) the background from the inelastic Compton process e+e− →...
