Deep inelastic electron-proton scattering

Summary, in English

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(−m_e²). 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⁻ → e⁺e⁻ + hadrons with C = −, which we find is controllable.
