# Are the new excited $\Omega_c$ baryons negative parity states?

## TL;DR

This paper uses QCD sum rules to calculate the masses and residues of newly observed excited Omega_c baryons, supporting their negative parity states with theoretical predictions matching experimental data.

## Contribution

It provides the first QCD sum rule analysis assigning negative parity quantum numbers to the Omega_c(3000) and Omega_c(3066) states.

## Key findings

- Predicted masses agree with experimental measurements.
- Confirmed negative parity quantum numbers for the states.
- Validated QCD sum rules as effective for baryon spectroscopy.

## Abstract

We calculate the mass and residue of the newly observed $\Omega_c(3000)$ and $\Omega_c(3066)$ states with quantum numbers $J^P = \frac{1}{2}^{-}$ and $\frac{3}{2}^{-}$ within QCD sum rules. Our predictions on masses are in good agreement with the experimental results.
