Measurement of the Parity-Violating Asymmetry in Electron-Deuteron Scattering in the Nucleon Resonance Region (The Jefferson Lab Hall A Collaboration)

China Institute of Atomic Energy, Beijing, 102413, P. R. China(Dated: April 30, 2013)We report on parity-violating asymmetries in the nucleon resonance region measured using 5 − 6 GeV lon-gitudinally polarized electrons scattering off an unpolarized deuterium target. These results are the first parity-violating asymmetry data in the resonance region beyond the ∆(1232), and provide a verification of quark-hadron duality in the nucleon electroweak γZ interference structure functions at the 10-15% level. The resultsare of particular interest to models relevant for calculating the γZ box-diagram corrections to elastic parity-violating electron scattering measurements.
