Available in PDF, EPUB and Kindle. Book excerpt: 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[sup 2]/c[sup 2] momentum transfer at JLab. From their 1998 run, this asymmetry is[minus]14.5[+-]2.2 ppm, consistent with the Standard Model with no contribution from strange quarks. They extract the combination of strange form factors G[sup 3][sub E]+ 0.39G[sup 3][sub M]=0.023[+-]0.034(stat)[+-]0.022(syst)[+-]0.026([delta]G[sup+n][sub E]), where the last error arises from the neutron electric form factor.

Book excerpt: 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/c[sup 2] 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 G[sub E][sup s]+ 0.39G[sub M][sup s]= 0.023[+-] 0.034(stat)[+-] 0.022(syst)[+-] 0.026[delta]G[sub E][sup n], where the last error arises from the neutron electric form factor.
