abstract

Inspired by the newly observed $P_{\psi s}^\Lambda(4338)$ and the reported $P_{cs}(4459)$, we indicate the existence of the molecular-type characteristic mass spectrum for hidden-charm pentaquark with strangeness. It shows that the $P_{cs}(4459)$ may contain two substructures corresponding to the $\Xi_c\bar{D}^*$ molecular states with $J^P=1/2^-$ and $3/2^-$, while there exists the corresponding $\Xi_c \bar{D}$ molecular state with $J^P=1/2^-$. As the prediction, we present another characteristic mass spectrum of the $\Xi_c^\prime\bar{D}^{(*)}$ molecular states. Experimental confirmation of these characteristic mass spectra is a crucial step of constructing hadronic molecular family.

    Coupled-channel OBE dynamics with S–D mixing produce three near-threshold poles dominated by BΣ/B*Σ that should show as narrow enhancements in open Bs0N, BΛ and B*Λ channels.
