Measurements of the strangeness content of the proton through parity violating electron scattering at JLAB
Description
The authors have measured the parity violating asymmetry in the cross section for elastic scattering of longitudinally polarized electrons from protons at 3.36 GeV incident energy and 0.48 GeV/c2 momentum transfer at Jefferson Lab. This asymmetry is (minus)14.5 ± 2.3 ppm, consistent with the Standard Model with no contribution from strange quarks. They extract the combination of strange form factors GEs + 0.39GMs = 0.023 ± 0.034(stat) ± 0.022(syst) ± 0.026(delta)GEn, where the last error arises from the neutron electric form factor
