Final Results of the GEp-III Experiment and the Status of the Proton Form Factors
Abstract
The recently published final results of experiment E04-108 in Jefferson Lab Hall C extend the recoil polarization measurements of the ratio of the proton electric and magnetic form factors to Q2 = 8.5 GeV2, an increase in Q2 coverage of more than 50%. A global fit of GpEand GpM to selected data for electron-proton elastic scattering cross sections and polarization observables is presented, illustrating the statistical impact of the new results.
