Abstract

Using the available cross-section and polarization data for elastic electron-proton scattering, we provide an extraction of the two-photon exchange amplitudes at a common value of four-momentum transfer, around Q 2 = 2.5 GeV^2. This analysis also predicts the e + p/e - p elastic-scattering cross-section ratio, which will be measured by forthcoming experiments.
