Near-Threshold J/$\ddot{I}ˆ\to \hat{I}{¼}^{+}\hat{I}{¼}^{-}$ 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/$\ddot{I}ˆ\to \hat{I}{¼}^{+}\hat{I}{¼}^{-}$ photoproduction from the J/$\ddot{I}ˆ$-007 experiment in Hall C at Jef…
