Kavli Affiliate: A. C. Davis | Summary:We report the measurement of the parity-violating asymmetry for the inelastic scattering of electrons from the proton, at $Q^2 = 0.082$ GeV$^2$ and $ W = 2.23$ GeV, above the resonance region. The result $A_rm Inel = – 13.5 pm 2.0 (rm stat) pm 3.9 (rm syst)$~ppm agrees with theoretical calculations, and helps to validate the modeling of the $γZ$ interference structure functions $F_1^γZ$ and $F_2^γZ$ used in those calculations, which are also used for determination of the two-boson exchange box diagram ($Box_γZ$) contribution to parity-violating elastic scattering measurements. A positive parity-violating asymmetry for inclusive $π^-$ production was observed, as well as positive beam-normal single-spin asymmetry for scattered electrons and a negative beam-normal single-spin asymmetry for inclusive $π^-$ production. | Search Query: arXiv Query: search_query=au:”Davis A.
