# The observed $\Omega_{c}^{0}$ resonances as pentaquark states

## TL;DR

This study explores the possibility that the recently observed $\\Omega_{c}^{0}$ resonances are pentaquark states, using a constituent quark model with Goldstone boson exchange to analyze low-lying $sscq\bar{q}$ configurations.

## Contribution

It provides a theoretical analysis showing certain $sscq\bar{q}$ pentaquark configurations match the energies of observed $\\Omega_{c}^{0}$ states, suggesting these resonances may have a pentaquark structure.

## Key findings

- Four configurations with specific quantum numbers are close in energy to observed states.
- The results support the pentaquark interpretation of $\\Omega_{c}^{0}$ resonances.
- The model indicates sizable pentaquark components in the observed resonances.

## Abstract

In present work, we investigate the spectrum of several low-lying $sscq\bar{q}$ pentaquark configurations employing the constituent quark model, within which the hyperfine interaction between quarks is taken to be mediated by Goldstone boson exchange. Our numerical results show that four $sscq\bar{q}$ configurations with $J^{P}=1/2^{-}$ or $J^{P}=3/2^{-}$ lie at energies very close to the recently observed five $\Omega_{c}^{0}$ states by LHCb collaboration, this indicates that the $sscq\bar{q}$ pentaquark configurations may form sizable components of the observed $\Omega_{c}^{0}$ resonances.
