Near-Threshold J/$\psi \to {\mu }^{+}{\mu }^{-}$ 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/$\psi \to {\mu }^{+}{\mu }^{-}$ photoproduction from the J/$\psi$-007 experiment in Hall C at Jeffers…
