A schematic model of baryons and mesons

Inspired by the newly observed PψsΛ(4338) and the reported Pcs(4459), we indicate the existence of the molecular-type characteristic mass spectrum for hidden-charm pentaquark with strangeness. It shows that the Pcs(4459) may contain two substructures corresponding to the ΞcD¯⁎ molecular states with JP=1/2− and 3/2−, while there exists the corresponding ΞcD¯ molecular state with JP=1/2−. As the prediction, we present another characteristic mass spectrum of the Ξc′D¯(⁎) molecular states. Experimental confirmation of these characteristic mass spectra is a crucial step of constructing hadronic molecular family.
