Canonical interpretations of the newly observed Ξc(2923)0, Ξc(2939)0, and Ξc(2965)0 resonances

Three neutral resonances Xi c(2923)0, Xi c(2939)0, and Xi c(2965)0 have been observed in the Lambda c+K- mass spectrum by the LHCb Collaboration. Given the Xi c and Xi c ' mass spectra predicted by the constituent quark models, these three resonances are tentatively treated as the lambda -mode Xi c(2S), Xi c '(2S), Xi c '(2S), and Xi c '(1P) states, and their strong decay behaviors are calculated within the 3P0 model. Our results indicate that the Xi c(2923)0 and Xi c(2939)0 can be clarified into the JP=3/2- and 5/2-Xi c '(1P) states respectively, and the Xi c(2965)0 can be regarded as the JP=1/2+Xi c ' (2S) state. Also, we suggest that the previous observed Xi c(2930) may be the overlap of two structures Xi c(2923) and Xi c(2939), and the Xi c(2970) should be the same state as Xi c(2965). Other theoretical information on the missing Xi c(2S), Xi c ' (2S), and Xi c ' (1P) states may be helpful for future experimental searches.
