      Status: Published

      Abstract:
    Very recently Belle Collaboration reported observation of a narrow state called Ω(2012) with mass [2012.4 ±0.7 (stat) ±0.6(syst)] MeV and width [6.4+2.5−2.0 (stat) ±1.6 (syst)] MeV. We calculate the mass and residue of Ω(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 Ω baryon, i.e. with quantum numbers JP=[3/2]−.
