| contents | The LHCb Collaboration has observed two types of hidden-charm pentaquark states $P_ψ^N$ and $P_{ψs}^Λ$ since 2015. In this work, we predict two other types of hidden-charm pentaquark states $P_{ψs}^Σ(4367)$ and $P_{ψss}^{N}(4379)$ within the framework of heavy pentaquark chiral perturbation theory. We suggest the LHCb Collaboration to observe $P_{ψss}^{N}(4379)^{-}$ and $P_{ψss}^{N}(4379)^0$ with $J^P=\frac{1}{2}^{-}$ in the $J/ψΞ$ spectrum through amplitude analyses of $Ω_b^- \to J/ψΞ^0 K^-$ decays and $B^- \to J/ψΞ^- \barΛ$ decays. |
