# Exotic pentaquark states with the $qqQQ\bar{Q}$ configuration

## TL;DR

This study uses the color-magnetic interaction model to predict masses and stability of triply heavy pentaquark states with the $qqQQar{Q}$ configuration, suggesting some may be stable or narrow and guiding experimental searches.

## Contribution

It provides systematic mass predictions and stability analysis for triply heavy pentaquarks with a specific quark configuration, a novel theoretical insight.

## Key findings

- Several stable or narrow pentaquark states may exist.
- Mass splittings are systematically calculated.
- Guidance for experimental searches is provided.

## Abstract

In the framework of the color-magnetic interaction model, we have systematically calculated the mass splittings for the S-wave triply heavy pentaquark states with the configuration $qqQQ\bar{Q}$ $(Q=c,b;q=u,d,s)$. Their masses are estimated and their stabilities are discussed according to possible rearrangement decay patterns. Our results indicate that there may exist several stable or narrow such states. We hope the present study can help experimentalists to search for exotic pentaquarks.
