Photoproduction of hidden charm pentaquark states $P_c^{+}(4380)$ and $P_c^{+}(4450)$

Abstract

We propose to study the pentaquark candidates of $P_c^{+}(4380)$ and $P_c^{+}(4450)$ in $J/\psi$ photoproduction and look for further experimental evidence for their nature. Since the photoproduction process does not satisfy the so-called "anomalous triangle singularity" condition their presence in $J/\psi$ photoproduction would conclude that they should be genuine states and provide further evidence for their existence.
