摘要
Very recently, LHCb Collaboration observed that two new Omega 0c states decay into Xi & thorn;c K- with masses of determined. In this paper, we exploit the quark-diquark model, the linear Regge trajectory and the perturbation treatment method to analyze the mass spectra of the discovered experimental data for the singly heavy baryons Sigma c/Sigma b, Xi 0c/Xi 0b, and Omega c/Omega b. In addition, we further predict the mass spectra of several unobserved Sigma c/Sigma b, Xi 0c/Xi 0b, and Omega c/Omega b baryons. In the case of the Omega c & eth;3185 & THORN;0 and Omega c & eth;3327 & THORN;0 states, we determine Omega c & eth;3185 & THORN;0 as 2S state and Omega c & eth;3327 & THORN;0 as 1D state with JP 1/4 1/2 & thorn; and JP 1/4 3/2 & thorn;, respectively. An overall good agreement of the obtained predictions with available experimental data are found.
