Disentangling the hadronic molecule nature of the Pc(4380) pentaquark-like structure

We demonstrate that the relative ratio of the decays of hidden charm pentaquark-like structure Pc+(4380) to D¯⁎Λc+ and J/ψpJ/ψp is very different for Pc+ being D¯Σc⁎(2520) or D¯⁎Σc(2455) molecule states. While the partial width of the D¯Σc⁎(2520) molecule to the D¯⁎Λc+ is much larger, by one order of magnitude, than that to the J/ψpJ/ψp, the D¯⁎Σc(2455) molecule shows a different pattern. Our analysis shows that the D¯Σc⁎ bound state ansatz is more reasonable than the D¯⁎Σc one to explain the broad Pc(4380)Pc(4380) structure. We suggest to search for the Pc(4380)Pc(4380) in the D¯⁎Λc+ system, which can be used to disentangle the nature of the Pc+(4380) structure.
