Abstract

The HAPPEX Collaboration measured parity-violating electron scattering from 4He(e, e) and H(e, e) in 2004 and 2005 for Q2 ≤ 0.11 GeV2. Results for the strange-quark contributions to the electromagnetic form factors of the nucleon from the 2004 data will be reviewed. Preliminary results from the 2005 data, which have significantly greater statistical precision, are GsE = 0.004 0.014stat 0.013syst for Q2 = 0.0772 GeV2 from the helium data and GsE + 0.088 GsM = 0.004 0.011stat 0.005syst 0.004FF for Q2 = 0.1089 GeV2 from the hydrogen data.

HAPPEX: Strange Quarks in the Proton and 4He

Journal Article Michaels, Robert - AIP Conference Proceedings

HAPPEX results from our 2005 run for the parity-violating asymmetry A PV in elastic scattering of 3 GeV electrons off hydrogen and 4He targets at <{theta}lab> {approx_equal} 6.0 deg. are presented. The 4He result is APV (+6.40 {+-} 0.23 (stat) {+-} 0.12 (syst)) x 10-6. The hydrogen result is APV = (-1.58 {+-} 0.12 (stat) {+-} 0.04 (syst)) x 10-6. The asymmetry for hydrogen is a linear combination of G{sub E}{sup s} and G{sub M}{sup s}, the strange quark contributions to the electric and magnetic form factors of the nucleon, respectively, and that for 4He is a function of G{submore »« less

The next generation HAPPEX experiments

Conference Holmes, Richard

A new generation of parity violating electron scattering experiments began running in Summer 2004 at the Thomas Jefferson National Accelerator Facility. HAPPEX-H will measure the parity violating asymmetry in polarized electron scattering from protons at Q2 = 0.11 (GeV/c)2. This asymmetry is sensitive to a linear combination of the strange electric and magnetic form factors of the proton. HAPPEX-He will measure the parity violating asymmetry in polarized electron scattering from a 4He target at the same value of Q2, using the same spectrometers and similar detectors, accessing the strange electric form factor cleanly. PREX will use parity violating electron scatteringmore »« less

Strangeness Contributions to the Static Properties of the Proton

Conference Paschke, Kent

Precision measurements of parity violation in electron-nucleus elastic scattering at low Q2 are sensitive to the strange quark magnetic moment and the strange-charge radius of the proton, and thus provide a unique opportunity to cleanly isolate the role of the quark- antiquark sea in low-energy Quantum Chromodynamics. While recent results have placed a tight upper-bound on strange quark contributions to the electric form-factor at low Q2, significant (~10%) contributions to the proton magnetic moment are still allowed by the existing data. Results from recently completed measurements of backward-angle scattering, by the G0 and A4 collaborations, will provide an improved sensitivitymore »« less
HAPPEX Parity Violation Experiments at Jefferson Lab

Conference Armstrong, David

The HAPPEX program of measurements of parity-violation in elastic electron scattering, in Hall A of Jefferson Lab, is presented. The results of the recently completed measurement on the proton at Q2 = 0.48 GeV2 are briefly reviewed. The plans are presented for the upcoming HAPPEX II measurement on the proton at Q2 = 0.1 GeV2, as well as the companion measurement with a 4He target at the same momentum transfer. These experiments are sensitive to strange quark contributions to the vector structure of the nucleon. The two new experiments will provide a precision measurement of the strangeness radius parameter, andmore »« less
Measurement of the Strange Quark Contribution to Proton Structure through Parity Violating Electron-Proton Scattering

Thesis/Dissertation Nakahara, Kazutaka

The G0 (G-Zero) forward angle experiment completed in Hall C of the Thomas Jefferson National Accelerator Facility (TJNAF) has measured the parity violating asymmetries in elastic electron-proton scattering over a Q2 range of 0.12 < Q2 < 1.0 (GeV/c)2. A linear combination of the strange electric (GsE) and magnetic (GsM) form factors calculated from these asymmetries indicate a non-zero contribution of the strange quark to the charge and magnetization structure of the proton in the above kinematic range at a 89% confidence level. The results show a previously unmeasured Q2 dependence of the strange form factors. Combining the G0 resultsmore »« less
