Abstract

Recent measurements of the neutron s electric to magnetic form factors ratio, R_n = μ_nGⁿ_E/G ⁿ_M, up to 3.4 (GeV/c)² combined with existing R_p = μ_pG^p_E/G^p _M measurements in the same Q² range allowed, for the first time, a separation of the up- and downquark contributions to the form factors at high Q², as presented by Cates, et al. Our analysis expands on the original work by including additional form factor data, applying two-photon exchange (TPE) corrections, and accounting for the uncertainties associated with all of the form factor measurements.
