Description

The experiment for unpolarized scattering using Rosenbluth method and the polarization extractions give different result of R = GE/GM at large Q2. This apparent discrepancy can be explained by a two-photon exchange correction. We find that the interference of one- and two-photon exchange contribution is able to substantially resolve the difference
