Initial results of the TRIUMF ultracold advanced neutron source
B. Algohi, D. Anthony, L. Barrón-Palos +83
We report the first results on ultracold neutron production from a new spallation-driven superfluid He (He-II) source at TRIUMF, which is being prepared for a new, precise meas…
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,…
Measurement of the Beam-Normal Single-Spin Asymmetry for Elastic Electron Scattering from C and Al
QWeak Collaboration, D. Androic, D. S. Armstrong +82
We report measurements of the parity-conserving beam-normal single-spin elastic scattering asymmetries on C and Al, obtained with an electron beam polarized tra…
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…
Parity-Violating Inelastic Electron-Proton Scattering at Low Above the Resonance Region
QWeak Collaboration, D. Androic, D. S. Armstrong +74
We report the measurement of the parity-violating asymmetry for the inelastic scattering of electrons from the proton, at GeV and GeV, above the reson…
Precision Measurement of the Weak Charge of the Proton
D. Androic, D. S. Armstrong, A. Asaturyan +96
The fields of particle and nuclear physics have undertaken extensive programs to search for evidence of physics beyond that explained by current theories. The observation of the Hi…
Early Results from the Qweak Experiment
D. Androic, D. S. Armstrong, A. Asaturyan +94
A subset of results from the recently completed Jefferson Lab Qweak experiment are reported. This experiment, sensitive to physics beyond the Standard Model, exploits the small par…
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…
The G0 Experiment: Apparatus for Parity-Violating Electron Scattering Measurements at Forward and Backward Angles
G0 Collaboration, D. Androic, D. S. Armstrong +127
In the G0 experiment, performed at Jefferson Lab, the parity-violating elastic scattering of electrons from protons and quasi-elastic scattering from deuterons is measured in order…
Transverse Beam Spin Asymmetries in Forward-Angle Elastic Electron-Proton Scattering
G0 Collaboration, D. S. Armstrong
We have measured the beam-normal single-spin asymmetry in elastic scattering of transversely-polarized 3 GeV electrons from unpolarized protons at Q^2 = 0.15, 0.25 (GeV/c)^2. The r…
Strange Quark Contributions to Parity-Violating Asymmetries in the Forward G0 Electron-Proton Scattering Experiment
The G0 Collaboration
We have measured parity-violating asymmetries in elastic electron-proton scattering over the range of momentum transfers 0.12 < Q^2 < 1.0 GeV^2. These asymmetries, arising from int…
Charge symmetry breaking in n p --> d pi^0
A. K. Opper, E. Korkmaz, D. A. Hutcheon +12
The forward--backward asymmetry in n p --> d pi^0, which must be zero in the center-of-mass system if charge symmetry is respected, has been measured to be [17.2 +/- 8 (stat) +/- 5…
Scattering of p muonic atoms in solid hydrogen
J. Wozniak, A. Adamczak, G. A. Beer +18
We present the results of experimental and theoretical study of the scattering of low energy p atoms in solid hydrogen cooled to 3 K. The resulting emission of low energy p a…
Pion-nucleus elastic scattering on 12C, 40Ca, 90Zr, and 208Pb at 400 and 500 MeV
George Kahrimanis, George Burleson, C. M. Chen +21
Pion-nucleus elastic scattering at energies above the Delta(1232) resonance is studied using both pi+ and pi- beams on 12C, 40Ca, 90Zr, and 208Pb. The present data provide an oppor…
