# Pentaquark photoproduction

## TL;DR

This paper discusses methods to confirm the existence of the pentaquark $Pc(4450)$ via photoproduction experiments, providing constraints on its properties and suggesting how to detect it more effectively.

## Contribution

It offers new experimental suggestions and constraints for detecting the $Pc(4450)$ pentaquark through photoproduction, addressing past detection challenges.

## Key findings

- The $Pc(4450)$ may have been missed in previous experiments.
- Constraints on the branching ratio to $J/\psi p$ are provided.
- Recommendations for future photoproduction detection methods.

## Abstract

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 $J/\psi p$ channel.
