      abstract     = {Three hidden-charm pentaquark Pc states, Pc(4312),
                      Pc(4440), and Pc(4457) were revealed in the Λ0b→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 distributions under the assumption that the
                      crossed-channel effects provide a smooth background. For the
                      first time, such an analysis is performed employing a
                      coupled-channel formalism with the scattering potential
                      involving both one-pion exchange as well as short-range
                      operators constrained by heavy quark spin symmetry. We find
                      that the data can be well described in the hadronic
                      molecular picture, which predicts seven Σ(*)c¯D(*)
                      molecular states in two spin multiplets, such that the
                      Pc(4312) is mainly a Σc¯D bound state with JP=1/2−,
                      while Pc(4440) and Pc(4457) are Σc¯D∗ bound states with
                      quantum numbers 3/2− and 1/2−, respectively. We also
                      show that there is evidence for a narrow Σ∗c¯D bound
                      state in the data which we call Pc(4380), different from the
                      broad one reported by LHCb in 2015. With this state
                      included, all predicted Σc¯D, Σ∗c¯D, and Σc¯D∗
                      hadronic molecules are seen in the data, while the missing
                      three Σ∗c¯D∗ states are expected to be found in future
                      runs of the LHC or in photoproduction experiments.},
