# On the nature of the newly discovered $\Omega_c^{0}$ states

## TL;DR

This paper uses QCD sum rules to calculate the properties of excited heavy baryons, specifically the $ ext{Omega}_c^{0}$ and $ ext{Omega}_b^{-}$ states, and compares results with recent LHCb observations.

## Contribution

It provides the first detailed QCD sum rule analysis of the radially excited $ ext{Omega}_c^{0}$ and $ ext{Omega}_b^{-}$ baryons, including vacuum condensates up to ten dimensions.

## Key findings

- Calculated masses and residues of excited $ ext{Omega}_c^{0}$ and $ ext{Omega}_b^{-}$ baryons.
- Made a comparison with recently observed narrow excited states by LHCb.
- Enhanced understanding of heavy baryon spectroscopy.

## Abstract

The masses and residues of the radially excited heavy $\Omega_c^{0}$ and $ \Omega_b^{-}$ baryons with spin-parity $J^{P}=\frac{1}{2}^{+}$ and $J^{P}= \frac{3}{2}^{+}$ are calculated by means of QCD two-point sum rule method using the general form of their interpolating currents. In calculations the quark, gluon and mixed vacuum condensates up to ten dimensions are taken into account. In $\Omega_c^{0}$ channel a comparison is made with the narrow excited states recently observed by the LHCb Collaboration.
