Near-Threshold J/ $ψ \to μ^{+} μ^{-}$ Photoproduction and the Gluonic Gravitational Form Factors of the Proton

007 Collaboration, S. Joosten, Z. -E. Meziani +56

We report on the measurement of the two-dimensional differential cross section for near-threshold J/ $ψ \to μ^{+} μ^{-}$ photoproduction from the J/ $ψ$ -007 experiment in Hall C at Jeffers…

Probing hard/soft factorization via beam-spin asymmetry in exclusive pion electroproduction from the proton

Alicia C. Postuma, Garth M. Huber, D. J. Gaskell +76

Deep exclusive meson production (DEMP) reactions, such as $p (e, e^{'} π^{+}) n$ , provide opportunities to study the three-dimensional structure of the nucleon through differential cr…

Quasielastic $^{3} He (e, e^{'})$ Asymmetry in the Threshold Region

M. Nycz, W. Armstrong, T. Averett +97

A measurement of the double-spin asymmetry from electron- $^{3}$ He scattering in the threshold region of two- and three-body breakup of $^{3}$ He was performed at Jefferson Lab, for…
