We propose to measure the parity-violating electroweak asymmetry A P V in the deep-inelastic scattering of polarized electrons (PVDIS) to high precision in order to search for physics beyond the Standard Model in lepton-quark neutral current interactions. Presently, the atomic parity-violation measurement in 133 Cs provides important limits on such new(More)
The neutron longitudinal and transverse asymmetries A n 1 and A n 2 have been extracted from deep inelas-tic scattering of polarized electrons by a polarized 3 He target at incident energies of 19.42, 22.66 and 25.51 GeV. The measurement allows for the determination of the neutron spin structure functions g n 1 (x; Q 2) and g n 2 (x; Q 2) over the range(More)
The inclusive A(e,eЈ) cross section for xӍ1 was measured on 2 H, C, Fe, and Au for momentum transfers Q 2 from 1 to 6.8 ͑GeV/c) 2. The scaling behavior of the data was examined in the region of transition from y scaling to x scaling. Throughout this transitional region, the data exhibit ␰ scaling, reminiscent of the Bloom-Gilman duality seen in free nucleon(More)
Separated longitudinal and transverse cross sections for charged pion electroproduction from 1 H, 2 H, and 3 He were measured at Q 2 ෇ 0.4 ͑GeV͞c͒ 2 for two values of the invariant mass, W ෇ 1.15 GeV and W ෇ 1.60 GeV, in a search for a mass dependence which would signal the effect of nuclear pions. This is the first such study that includes recoil momenta(More)

In virtual Compton scattering an electron is scattered off a nucleon such that the nucleon emits a photon. We show that these events can be selected experimentally, and present the first evidence for virtual Compton scattering from the proton in data obtained at the Stanford Linear Accelerator Center. The angular and energy dependence of the data is well(More)
We study nuclear effects of charged current deep inelastic neutrino-iron scattering in the framework of a χ 2 analysis of parton distribution functions (PDFs). We extract a set of iron PDFs which are used to compute xBj-dependent and Q 2-dependent nuclear correction factors for iron structure functions which are required in global analyses of free nucleon(More)
Inclusive scattering from nuclei at x > 1 is sensitive to the distribution of high momentum nucleons at low Q 2 values, and high momentum quarks at large Q 2 values. Large x data at 4 and 6 GeV are dominated by quasielastic and resonance production from high-momentum nucleons. With the 11 GeV beam, we propose to make measurements in the DIS region and(More)
