# Interpretation of the new $\Omega_c^{0}$ states via their mass and width

## TL;DR

This paper uses QCD sum rules to analyze the masses, widths, and quantum numbers of excited $\,Omega_c^{0}$ baryons, matching theoretical predictions with recent LHCb experimental data to interpret their structure.

## Contribution

It provides a detailed QCD sum rule analysis of $\,Omega_c^{0}$ states, assigning quantum numbers and interpreting experimental resonances as specific excited baryons.

## Key findings

- $\,Omega_c(3000)^{0}$ as $1P, 1/2^{-}$ state
- $\,Omega_c(3050)^{0}$ as $1P, 3/2^{-}$ state
- $\,Omega_c(3119)^{0}$ as $2S, 3/2^{+}$ state

## Abstract

The mass and pole residue of the ground and first radially excited $ \Omega_c^{0}$ states with spin-parities $J^{P}=1/2^{+},\,3/2^{+}$, as well as P-wave $\Omega_c^{0}$ with $J^{P}=1/2^{-},\,3/2^{-}$ are calculated by means of the two-point QCD sum rules. The strong decays of $\Omega_c^{0}$ baryons are also studied and width of these decay channels are computed. The relevant computations are performed in the context of the full QCD sum rules on the light-cone. Obtained results for the masses and widths are confronted with recent experimental data of LHCb Collaboration, which allow us to interpret $\Omega_c(3000)^{0}$, $\Omega_c(3050)^{0}$, and $ \Omega_c(3119)^{0} $ as the excited $css$ baryons with the quantum numbers $ (1P,\,1/2^{-})$, $(1P,\,3/2^{-})$, and $(2S,\,3/2^{+})$, respectively. The $ (2S,\,1/2^{+})$ state can be assigned either to $\Omega_c(3066)^{0}$ state or $\Omega_c(3090)^{0}$ excited baryon.
