# Hidden-charm Pentaquark Production at $e^+e^-$ Colliders

## TL;DR

This paper investigates the production mechanisms of hidden-charm pentaquarks at e+e- colliders, highlighting potential signals at B factories and Z^0 pole energies to aid in understanding pentaquark properties.

## Contribution

It introduces a new production mechanism via color-octet c c̄ pair fragmentation and analyzes its significance at different collider energies.

## Key findings

- Production dominated by e+e- to c c̄ g to Pc + X at B factories.
- Multiple partonic processes contribute at Z^0 pole energies.
- Potential for direct pentaquark detection at e+e- colliders.

## Abstract

We study one possible production mechanism for hidden charm pentaquark in e+e- collision, where it is produced via a color-octet c \bar c pair fragmentation. The pentaquark production at B factory energy is dominated by e+e- to c \bar c g to Pc + X. At Z^0 pole, for the pentaquark production, there are several partonic processes playing significant role. Our results show that it is possible to search for the direct pentaquark production signal at e+e- colliders, which is important to understand the properties of pentaquark.
