Measurement of the Parity-Violating Asymmetry in the N to Transition at Low
D. Adhikari, T. Alshayeb, D. Androic +70
We report the measurement of the parity-violating asymmetry in the N to transition via the reaction at two different kinematic points with low f…
First Determination of the Weak Charge of the Proton
Qweak Collaboration, D. Androic, D. S. Armstrong +95
The Qweak experiment has measured the parity-violating asymmetry in polarized e-p elastic scattering at Q^2 = 0.025(GeV/c)^2, employing 145 microamps of 89% longitudinally polarize…
Measurement of the Neutron Radius of 208Pb Through Parity-Violation in Electron Scattering
S. Abrahamyan, Z. Ahmed, H. Albataineh +132
We report the first measurement of the parity-violating asymmetry A_PV in the elastic scattering of polarized electrons from 208Pb. A_PV is sensitive to the radius of the neutron d…
New Precision Limit on the Strange Vector Form Factors of the Proton
HAPPEX collaboration, Z. Ahmed, K. Allada +102
The parity-violating cross-section asymmetry in the elastic scattering of polarized electrons from unpolarized protons has been measured at a four-momentum transfer squared Q2 = 0.…
