Delta(1232) contribution to real radiative corrections for elastic electron-proton scattering
The contradiction currently exists in the results of proton electromagnetic form factors measurements. More accurate calculation of radiative corrections to electron-proton elastic scattering cross section is one of the possible solutions of this problem. Here we consider a potential contribution of Delta(1232) resonance to real radiative corrections. The effect is found to be small for past experiments to measure the unpolarized ep-scattering cross section as well as for the recent experiment at the VEPP-3 storage ring to investigate the two-photon exchange effects.
