Two-photon exchange contribution in elastic electron-proton scattering, experiment at the VEPP-3 storage ring
We describe a precise measurement of the ratio of the (e+ p) to (e− p) elastic scattering cross sections. This comparison is sensitive to the effect of two-photon exchange contributions which may be the cause for inconsistent extractions of the proton form factors obtained using different methods....
