JLab and J-PARC for the J/{\ensuremathψ} Production at the Threshold

Igor I. Strakovsky, Jung Keun Ahn, William J. Briscoe +2

New threshold measurements for $γ p \to p J / ψ \to p (μ^{+} μ^{-})$ by 007 and $γ^{*} p \to p J / ψ \to p (e^{+} e^{-})$ by CLAS12 allow us to extend the previous phenomenological determination of…

Near-threshold photoproduction of $Λ (1520)$ from protons and deuterons

LEPS Collaboration, N. Muramatsu, J. Y. Chen +53

Photoproduction of $Λ$ (1520) with liquid hydrogen and deuterium targets was examined at photon energies below 2.4 GeV in the SPring-8 LEPS experiment. For the first time, the diffe…
