Form factors and two-photon exchange in high-energy elastic electron-proton scattering

We report new precision measurements of the elastic electron-proton scattering cross section for momentum transfer squared (Q^2) up to 15.75~\gevsq. These data allow for improved extraction of the proton magnetic form factor at high Q^2 and nearly double the Q^2 range of direct longitudinal/transverse separated cross sections. A comparison of...
