Radiative Corrections to Electron-Proton Scattering

Abstract

The radiative corrections to electron-proton scattering are calculated for an experiment in which the recoil proton is detected instead of the scattered electron. The emission of very hard photons by the scattered electrons is taken into account in the phase-space integration. This calculation is intended for high-energy experiments (up to 5 Bev) but is applicable whenever the momentum resolution of the spectrometer is small, i.e., ($\frac{\Delta P_4}{P_4}\lesssim 0.1$). Mesonic contributions to the two-photon exchange diagrams are neglected.
