$J/\ddot{I}ˆ$ photoproduction: threshold to very high energy

Lin Tang, Yi-Xuan Yang, Zhu-Fang Cui +1

A reaction model for ${\hat{I}}^3+p\to J/\ddot{I}ˆ+p$ photoproduction, which exposes the $c\bar{c}$ content of the photon in making the transition ${\hat{I}}^3\to c\bar{c}+\mathbb{P}\to J/\ddot{I}ˆ$ and coupl…
