Abstract

The GEp-III and GEp-2γ experiments, carried out in Jefferson Lab's Hall C from 2007–2008, consisted of measurements of polarization transfer in elastic electron–proton scattering at momentum transfers of Q 2 =2.5,5.2,6.8, and 8.54 GeV 2 . These measurements were carried out to improve knowledge of the proton electromagnetic form factor ratio R=μ p G E p ∕G M p at large values of Q 2 and to search for effects beyond the Born approximation in polarization transfer observables at Q 2 =2.5GeV 2 . The final results of both experiments were reported in a recent archival publication. A full reanalysis of the data from both experiments was carried out in order to reduce the systematic and, for the GEp-2γ experiment, statistical uncertainties. This technical note provides additional details of the final analysis omitted from the main publication, including the final evaluation of the systematic uncertainties.
