Radiative corrections for(e,e′p)reactions at GeV energies

Abstract

A general framework for applying radiative corrections to ${(e,e}^{\ensuremath{'}}p)$ coincidence reactions at GeV energies is presented, with special emphasis to higher-order bremsstrahlung effects, radiation from the scattered hadron, and the validity of peaking approximations. The sensitivity to the assumptions made in practically applying radiative corrections to ${(e,e}^{\ensuremath{'}}p)$ data is extensively discussed. The general framework is tested against experimental data of the ${}^{1}\mathrm{H}{(e,e}^{\ensuremath{'}}p)$ reaction at momentum transfer values larger than $1.0 (\mathrm{GeV}{/c)}^{2},$ where radiative processes become a dominant source of uncertainty. The formulas presented here can easily be modified for any other electron-induced coincidence reaction.
