Are the new excited ${\Omega }_c$ baryons negative parity states?

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.
