Interpretation of the newly discovered $\mathrm{\Omega }$(2012)

Very recently Belle Collaboration reported observation of a narrow state called $\mathrm{\Omega }(2012)$ with mass $2012.4\pm 0.7$~(stat)~$\pm 0.6$(syst)~MeV and width $6.4_{-2.0}^{+2.5}$~(stat)~$\pm 1.6$~(syst)~MeV. We calculate the mass and residue of $\mathrm{\Omega }(2012)$ state by employing the QCD sum rule method. Comparison of the obtained results with the experimental data allows us to interpret this state as $1P$ orbital excitation of the ground state $\mathrm{\Omega }$ baryon, i.e. with quantum numbers $J^P={\frac{3}{2}}^{-}$.
