Abstract

Unpolarized electron-proton elastic scattering cross-section measurements at high Q2Q^2 allow for improved extractions of the proton electromagnetic form factors as well as provide constraints on possible hard two-photon exchange effects. We present a detailed study of the feasibility of making these high Q2Q^2 e-p elastic measurements at the future Electron-Ion Collider (EIC). The results show that e-p elastic cross sections can be obtained in the momentum transfer range of 6 (GeV/c)2<Q2<40 (GeV/c)26~(GeV/c)^2 < Q^2 < 40~(GeV/c)^2, which would be the highest-ever Q2Q^2 values measured. These data will all be at virtual photon polarizations close to unity, ϵ1\epsilon \sim 1.
