【 摘 要 】

We present results and suggestions on how to confirm the existence and resonant nature of the Pc(4450) detected at LHCb through photoproduction experiments. We find that this narrow structure might have escaped detection in past experiments and use those to give a constraint for the upper limit of the branching ratio/coupling to the J/ψ p channel.
