Interpretation of the new Ωc0 states via their mass and width

The masses and pole residues of the ground and first radially excited Ωc0 states with spin–parities JP=1/2+,3/2+ , as well as P -wave Ωc0 with JP=1/2-,3/2- are calculated by means of the two-point QCD sum rules. The strong decays of Ωc0 baryons are also studied and the widths of these decay channels are computed. The relevant computations are performed in the context of the full QCD sum rules on the light cone. The results obtained for the masses and widths are confronted with recent experimental data of the LHCb Collaboration, which allow us to interpret Ωc(3000)0 , Ωc(3050)0 , and Ωc(3119)0 as the excited css baryons with the quantum numbers (1P,1/2-) , (1P,3/2-) , and (2S,3/2+) , respectively. The (2S,1/2+) state can be assigned either to the Ωc(3066)0 state or the Ωc(3090)0 excited baryon.
