Abstract

We report on parity-violating asymmetries in the nucleon resonance region measured using 5 - 6 GeV longitudinally polarized electrons scattering off an unpolarized deuterium target. These results are the first parity-violating asymmetry data in the resonance region beyond the Δ(1232), and provide a verification of quark-hadron duality in the nucleon electroweak γ Z interference structure functions at the (10-15)% level. The results are of particular interest to models relevant for calculating the γ Z box-diagram corrections to elastic parity-violating electron scattering measurements.

Measurement of parity-violating asymmetry in electron-deuteron inelastic scattering

Journal Article Wang, D. ; Pan, K. ; Subedi, R. ; ... - Physical Review C, Nuclear Physics

The parity-violating asymmetries between a longitudinally-polarized electron beam and an unpolarized deuterium target have been measured recently. The measurement covered two kinematic points in the deep inelastic scattering region and five in the nucleon resonance region. We provide here details of the experimental setup, data analysis, and results on all asymmetry measurements including parity-violating electron asymmetries and those of inclusive pion production and beam-normal asymmetries. The parity-violating deep-inelastic asymmetries were used to extract the electron-quark weak effective couplings, and the resonance asymmetries provided the first evidence for quark-hadron duality in electroweak observables. These electron asymmetries and their interpretation were publishedmore »« less

Measurement of the Parity-Violating Asymmetry in Deep Inelastic Scattering at JLab 6 GeV

Thesis/Dissertation Wang, Diancheng

The parity-violating asymmetry in deep inelastic scattering (PVDIS) offers us a useful tool to study the weak neutral couplings and the hadronic structure of the nucleon, and provides high precision tests on the Standard Model. During the 6 GeV PVDIS experiment at the Thomas Jefferson National Accelerator Facility, the parity-violating asymmetries A{sub PV} of a polarized electron beam scattering off an unpolarized deuteron target in the deep inelastic scattering region were precisely measured at two Q² values of 1.1 and 1.9 (GeV/c)². The asymmetry at Q²=1.9 (GeV/c)² can be used to extract the weak coupling combination 2C_2u - C_2d, assumingmore »« less

Measurement of the parity-violating asymmetry in inclusive electroproduction of π^- near the Delta⁰ resonance

Journal Article Androic, D. ; Armstrong, D. S. ; Bailey, S. L. ; ... - Physical Review Letters

The parity-violating (PV) asymmetry of inclusive π^- production in electron scattering from a liquid deuterium target was measured at backward angles. The measurement was conducted as a part of the G0 experiment, at a beam energy of 360 MeV. The physics process dominating pion production for these kinematics is quasi-free photoproduction off the neutron via the Δ⁰ resonance. In the context of heavy-baryon chiral perturbation theory (HBχPT), this asymmetry is related to a low energy constant d_Δ^- that characterizes the parity-violating γNΔ coupling. Zhu et al. calculated d_Δ^- in a model benchmarked by the large asymmetries seen in hyperon weakmore »« less
