Two-photon exchange from intermediate state resonances in elastic electron-proton scattering

NUCLEAR REACTIONS ¹H(e, e), at Q²<5 GeV²; calculated two-photon exchange (TPE) correction due to finite width of three significant resonance intermediate states Δ(1232), N(1520) and N(1720), TPE form factors, ratio R_2γ of e⁺+p to e^-+p elastic scattering cross sections, ratio of the proton electric to magnetic form factors. Dispersive approach for the two-photon exchange (TPE) correction to elastic electron-proton scattering. Comparison with experimental data from CLAS, VEPP-3 and OLYMPUS collaborations, and from other laboratories.
