Revisiting the nature of the P c pentaquarks

Abstract The nature of the three narrow hidden-charm pentaquark P c states, i.e., P c (4312), P c (4440) and P c (4457), is under intense discussion since their discovery from the updated analysis of the process Λ b 0 → J / ψ pK − $$ {\Lambda}_b^0\to J/\psi {pK}^{-} $$ by LHCb. In this work we exten...
