AbstractAbstract
[en] We report the results of a new Rosenbluth measurement of the proton form factors at Q2 values of 2.64, 3.20 and 4.10 GeV2. Cross sections were determined by detecting the recoiling proton in contrast to previous measurements in which the scattered electron was detected. At each Q2, relative cross sections were determined to better than 1%. The measurement focused on the extraction of GE/GM which was determined to 4-8% and found to approximate form factor scaling, i.e. μpGE ∼ GM. These results are consistent with and much more precise than previous Rosenbluth extractions. However, they are inconsistent with recent polarization transfer measurements of comparable precision, implying a systematic difference between the two techniques

AbstractAbstract
[en] We have measured the nuclear transparency of the A(e,e' pi+) process in 2H,12C, 27Al, 63Cu and 197Au targets. These measurements were performed at the Jefferson Laboratory over a four momentum transfer squared range Q2 = 1.1 - 4.7 (GeV/c)2. The nuclear transparency was extracted as the super-ratio of σAσH from data to a model of pion-electroproduction from nuclei without pi-N final state interactions. The Q2 and atomic number dependence of the nuclear transparency both show deviations from traditional nuclear physics expectations, and are consistent with calculations that include the quantum chromodynamical phenomenon of color transparency

AbstractAbstract
[en] The first complete measurements of the angular distributions of the two-body deuteron photodisintegration differential cross section at photon energies above 1.6 GeV were performed at the Thomas Jefferson National Accelerator Facility. The results show a persistent forward-backward asymmetry up to Egamma = 2.4 GeV, the highest-energy measured in this experiment. The Hard Rescattering and the Quark-Gluon string models are in fair agreement with the results

AbstractAbstract
[en] The deuteron elastic structure function A(Q2) has been extracted in the range 0.7 < or = Q2 < or = 6.0 (GeV/c)2 from cross section measurements of elastic electron-deuteron scattering in coincidence using the Hall A Facility of Jefferson Laboratory. The data are compared to theoretical models, based on the impulse approximation with the inclusion of meson-exchange currents, and to predictions of quark dimensional scaling and perturbative quantum chromodynamics
