Final Results of the GEp-III Experiment and the Status of the Proton Form Factors

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 $Q^2 = 8.5$ GeV$^2$, an increase in $Q^2$ coverage of more than 50%. A global fit of $G_E^p$ and $G_M^p$ to selected data for electron-proton elastic scattering cross sections and polarization observables is presented, illustrating the statistical impact of the new results.
