Studying the Pc(4450) resonance in J/psi photoproduction off protons

Understand

The LHCb has reported the observation of a resonancelike structure, the Pc(4450), in the J/psi p invariant masses.

• In our work, we discuss the feasibility of detecting this structure in J/psi photoproduction, e.g.
• in the measurements that have been approved for the experiments in Hall A/C and in Hall B with CLAS12 at JLab.
• Also the GlueX Collaboration has already reported preliminary results.
