First Determination of the 27Al Neutron Distribution Radius from a Parity-Violating Electron Scattering Measurement
QWeak Collaboration, D. Androic, D. S. Armstrong +91
We report the first measurement of the parity-violating elastic electron scattering asymmetry on 27Al. The 27Al elastic asymmetry is A_PV = 2.16 +- 0.11 (stat) +- 0.16 (syst) ppm,…
Precision Measurement of the Beam-Normal Single-Spin Asymmetry in Forward-Angle Elastic Electron-Proton Scattering
QWeak collaboration, D. Androic, D. S. Armstrong +92
A beam-normal single-spin asymmetry generated in the scattering of transversely polarized electrons from unpolarized nucleons is an observable related to the imaginary part of the…
Direct Measurement of Nuclear Dependence of Charged Current Quasielastic-like Neutrino Interactions using MINERvA
M. Betancourt, A. Ghosh, T. Walton +53
Charged-current interactions on carbon, iron, and lead with a final state hadronic system of one or more protons with zero mesons are used to investigate the influence of t…
High Resolution Spectroscopic Study of Be
T. Gogami, C. Chen, D. Kawama +83
Spectroscopy of a Be hypernucleus was carried out at JLab Hall C using the reaction. A new magnetic spectrometer system (SPL+HES+HKS), specifically…
A Precision Measurement of the Neutron Twist-3 Matrix Element : Probing Color Forces
M. Posik, D. Flay, D. S. Parno +89
Double-spin asymmetries and absolute cross sections were measured at large Bjorken (0.25 0.90), in both the deep-inelastic and resonance regions, by scattering lo…
Recoil Polarization Measurements of the Proton Electromagnetic Form Factor Ratio to Q^2 = 8.5 GeV^2
A. J. R. Puckett, E. J. Brash, M. K. Jones +103
Among the most fundamental observables of nucleon structure, electromagnetic form factors are a crucial benchmark for modern calculations describing the strong interaction dynamics…
