Abstract

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=(1)/(2)^- in the J/ψΞ spectrum through amplitude analyses of Ω_b^- → J/ψΞ⁰ K^- decays and B^- → J/ψΞ^- Λ decays.
