# Quantum Numbers of Recently Discovered $\Omega^{0}_{c}$ Baryons from Lattice QCD

## TL;DR

This study uses lattice QCD to determine the quantum numbers of recently observed $\,Omega_c^{0}"$ baryons, providing theoretical predictions for their spins and parities that match experimental findings.

## Contribution

The paper offers the first lattice QCD calculations of $\,Omega_c^{0}"$ baryon spectra with high spin states, predicting quantum numbers for recently observed particles.

## Key findings

- Identified quantum numbers for five $\,Omega_c^{0}"$ states.
- Predicted $\,Omega_c(3000)^0$ and $\,Omega_c(3050)^0$ as $J^P=1/2^{-}$.
- Suggested $\,Omega_c(3119)^0$ as possibly $5/2^{-}$.

## Abstract

We present the ground and excited state spectra of $\Omega^{0}_{c}$ baryons with spin up to 7/2 from lattice quantum chromodynamics with dynamical quark fields. Based on our lattice results, we predict the quantum numbers of five $\Omega^{0}_{c}$ baryons, which have recently been observed by the LHCb Collaboration. Our results strongly indicate that the observed states $\Omega_c(3000)^0$ and $\Omega_c(3050)^0$ have spin-parity $J^P = 1/2^{-}$, the states $\Omega_c(3066)^0$ and $\Omega_c(3090)^0$ have $J^P = 3/2^{-}$, whereas $\Omega_c(3119)^0$ is possibly a $5/2^{-}$ state.
