a Precise Measurement of the Proton Elastic Form Factors for 1.75 Less than or Equal to Q(2) <= 8.83 (GEV/C)(2)
Abstract
The proton elastic electric and magnetic form factors, G_{Ep}(Q^2) and G_{Mp}(Q^2), have been separated out to Q^2 of 8.83 (GeV/c)^2, more than doubling the Q^2 range of previous data. The results for G_{Mp}(Q ^2)/mu_{p}G_{D }(Q^2) decrease smoothly from 1.05 to 0.92, while G_{Ep}(Q^2)/G _{D}(Q^2) is consistent with unity. Comparisons are made to QCD Sum Rule, diquark, constituent quark, and VMD models, none of which agree with all of the new data. The ratio Q^2F _2/F_1 approaches a constant value for Q^2 > 3 (GeV/c)^2..
