We use the world's data on elastic electron-proton scattering and calculations of two-photon exchange effects to extract corrected values of the proton's electric and magnetic form factors over the full Q{sup 2} range of the existing data. Our analysis combines the corrected Rosenbluth cross section and polarization transfer data, and is the first extraction of G{sub E} and G{sub M} including explicit two-photon exchange corrections and their associated uncertainties. In addition, we examine the angular dependence of the corrected cross sections to examine the possible nonlinearities of the cross section as a function of {epsilon}.

Baryons as relativistic three-quark bound states (2016, background): “It is established by now that two-photon exchange corrections can explain the discrepancy in principle [573, 574], although the effect is still not completely understood because it cannot be calculated model-independently and the existing model calculations rely on different underlying mechanisms.”
