The Strange Quark Contribution to the Proton’s Magnetic Moment
(2004-03)
We report a new determination of the strange quark contribution to the proton’s magnetic form factor at a four-momentum transfer Q2 = 0.1(GeV/c)2 from parity-violating e-p elastic scattering. The result uses a revised ...
Parity-violating Electron Deuteron Scattering and the Proton’s Neutral Weak Axial Vector Form Factor
(2004-03)
We report on a new measurement of the parity-violating asymmetry in quasielastic electron scat- tering from the deuteron at backward angles at Q2 = 0.038 (GeV/c)2. This quantity provides a de- termination of the neutral ...
Measurement of the vector analyzing power in elastic electron-proton scattering as a probe of double photon exchange amplitudes
(2001-05)
We report the first measurement of the vector analyzing power in inclusive transversely polarized elastic electron-proton scattering at Q2 = 0.1 (GeV/c)2 and large scattering angles. This quantity should vanish in the ...
Strange Quark Contributions to Parity-Violating Asymmetries in the Forward G0 Electron-Proton Scattering Experiment
(2010-01)
We have measured parity-violating asymmetries in elastic electron-proton scattering over the range of momentum transfers 0.12 ≤ Q2 ≤ 1.0 GeV2. These asymmetries, arising from interference of the electromagnetic and neutral ...
Measurements of Deuteron Photodisintegration up to 4.0 GeV
(American Physical Society, 1998-11-23)
The first measurements of the differential cross section for the d(γ,p)n reaction up to 4.0 GeV were performed at the Continuous Electron Beam Accelerator Facility (CEBAF) at Thomas Jefferson Laboratory. We report the cross ...
Strange-Quark Contributions to Parity-Violating Asymmetries in the Forward G0 Electron-Proton Scattering Experiment
(American Physical Society, 2005-08-26)
We have measured parity-violating asymmetries in elastic electron-proton scattering over the range of momentum transfers 0.12≤Q2≤1.0 GeV2. These asymmetries, arising from interference of the electromagnetic and neutral ...
Parity Violation in Elastic Electron-Proton Scattering and the Proton's Strange Magnetic Form Factor
(American Physical Society, 2000-02-07)
We report a new measurement of the parity-violating asymmetry in elastic electron scattering from the proton at backward scattering angles. This asymmetry is sensitive to the strange magnetic form factor of the proton as ...
He→3(e→e′) quasielastic asymmetry
(1993-01)
Measurements of the spin-dependent asymmetry in scattering longitudinally polarized electrons from polarized He3 at quasielastic kinematics are reported. The measurements were made at two kinematics and spin angles, one ...
Transverse Beam Spin Asymmetries in Forward-Angle Elastic Electron-Proton Scattering
(American Physical Society, 2007-07-31)
We have measured the beam-normal single-spin asymmetry in elastic scattering of transversely polarized 3 GeV electrons from unpolarized protons at Q2=0.15, 0.25 (GeV/c)2. The results are inconsistent with calculations ...
Measurement of the neutron magnetic form factor from inclusive quasielastic scattering of polarized electrons from polarized 3He
(1994-08)
We report a measurement of the asymmetry in spin-dependent quasielastic scattering of longitudinally polarized electrons from a polarized 3He target. The neutron magnetic form factor GMn has been extracted from the measured ...
