Understand

LHCb recently announced the discovery of two exotic structures in the $J/\psi + p$ decay channel, which have been referred to as charmonium-pentaquark states.

Resolving between the models and clarifying the nature of the discovered hidden-charm pentaquark peaks, and possibly searching for similar peaks with other quantum numbers, requires further experimental studies.
The states were observed in the decay mode $J/\psi+p$.
Thus, it is natural to expect that these pentaquarks can be produced in the photoproduction process $\gamma+p\to P_c\to J/\psi+p$ where these states will appear as s-channel resonances at photon energy around 10 GeV.
