Interpretation of the LHCb Pc States as Hadronic Molecules and Hints of a Narrow Pc(4380)

Three hidden-charm pentaquark Pc states, Pc(4312), Pc(4440), and Pc(4457) were revealed in the Λb0→J/ψpK− process measured by LHCb using both run I and run II data. Their nature is under lively discussion, and their quantum numbers have not been determined. We analyze the J/ψp invariant mass distrib...
