Abstract

We report measurements of the proton elastic form factors, G_E^p and G_M^p, extracted from electron scattering in the range 1≤Q²≤3(GeV/c)². The uncertainties are <15% in G_E^p and <3% in G_M^p. The values of G_E^p are larger than indicated by most theoretical parameterizations, The ratio of Pauli and Dirac form factors, Q²F₂^p/F₁^p, is lower and demonstrates less Q² dependence than most of these parameterizations. Comparisons are made to theoretical models, including those based on perturbative QCD and vector-meson dominance.
