  • Measurements of parity-violating asymmetries in electron-deuteron scattering in the nucleon resonance region
    Wang, D., fizik ...
    We report on parity-violating asymmetries in the nucleon resonance region measured using inclusive inelastic scattering of 5-6 GeV longitudinally polarized electrons off an unpolarized deuterium ... target. These results are the first parity-violating asymmetry data in the resonance region beyond the ▫$\Delta$▫ (1232). They provide a verification of quark-hadron duality - the equivalence of the quark- and hadron-based pictures of the nucleon - at the (10-15)% level in this electroweak observable, which is dominated by contributions from the nucleon electroweak ▫$\gamma$▫Z interference structure functions. In addition, the results provide constraints on nucleon resonance models relevant for calculating background corrections to elastic parity-violating electron scattering measurements.
