Abstract
We report measurements of the proton form factors and extracted from elastic scattering in the range with total uncertainties < 15% in and < 3% in . Comparisons are made to theoretical models, including those based on perturbative QCD, vector-meson dominance, QCD sum rules, and diquark constituents in the proton. The results for are somewhat larger than indicated by most theoretical parametrizations, and the ratios of the Pauli and Dirac form factors are lower in value and demonstrate a weaker dependence than those predictions. A global extraction of the elastic form factors from several experiments in the range 0.1 is also presented.
