Newly observed Ω (2012) state and strong decays of the low-lying Ω excitations

Abstract

Stimulated by the newly discovered Ω(2012) resonance at Belle II, in this work we have studied the OZI allowed strong decays of the low-lying 1P- and 1D-wave Ω baryons within the P03 model. It is found that Ω(2012) is most likely to be a 1P-wave Ω state with JP=3/2-. We also find that the Ω(2250) state could be assigned as a 1D-wave state with JP=5/2+. The other missing 1P- and 1D-wave Ω baryons may have large potentials to be observed in their main decay channels.
