Interpretation of the newly discovered $\Omega \left(2012\right)$

Very recently, Belle Collaboration reported observation of a narrow state called $\Omega \left(2012\right)$ with mass $2012.4±0.7\left(\mathrm{stat}\right)±0.6\left(\mathrm{syst}\right)\text{}\mathrm{MeV}$ and width $6.{4}_{-2.0}^{+2.5}\left(\mathrm{stat}\right)±1.6\left(\mathrm{syst}\right)\text{}\mathrm{MeV}$. We calculate the mass and residue of the $\Omega \left(2012\right)$ state by employing the QCD sum rule method. Comparison of the obtained results with the experimental data allows us to interpret this state as a $1P$ orbital excitation of the ground state $\Omega $ baryon, i.e., with quantum numbers ${J}^{P}={\frac{3}{2}}^{-}$.
