A narrow pentaquark state, P c ( 4312 ) ⁺ , decaying to J / ψ p , is discovered with a statistical significance of 7.3 σ in a data sample of Λ 0 b → J / ψ p K − decays, which is an order of magnitude larger than that previously analyzed by the LHCb Collaboration. The P c ( 4450 ) ⁺ pentaquark structure formerly reported by LHCb is confirmed and observed to consist of two narrow overlapping peaks, P c ( 4440 ) ⁺ and P c ( 4457 ) ⁺ , where the statistical significance of this two-peak interpretation is 5.4 σ . The proximity of the Σ ⁺ c ¯ D 0 and Σ ⁺ c ¯ D * 0 thresholds to the observed narrow peaks suggests that they play an important role in the dynamics of the...
