Comment on "High-Precision Determination of the Electric and Magnetic Form Factors of the Proton"
arXiv:1108.3058 · doi:10.1103/PhysRevLett.107.119101
Abstract
In a recent Letter, Bernauer, et al. present fits to the proton electromagnetic form factors, GEp(Q^2) and GMp(Q^2), along with extracted proton charge and magnetization radii based on large set of new, high statistical precision (<0.2%) cross section measurements. The Coulomb corrections they apply differ dramatically from more modern and complete calculations, implying significant error in their final results.
