Prediction of hidden-charm pentaquarks with double strangeness

Inspired by the recent evidence of P-cs (4459) reported by LHCb, we continue to perform the investigation of hidden-charm molecular pentaquarks with double strangeness, which are composed of an S-wave charmed baryon Xi((')(,)(c) *()) and an S-wave anticharmed-strange meson (D) over bar (()(s)*()). Both the S-D wave mixing effect and the coupled channel effect are taken into account in realistic calculation. A dynamics calculation shows that there may exist two types of hidden-charm molecular pentaquark with double strangeness, i.e., the Xi(c)'(D) over bar (s)* molecular state with J(P) = 5/2(-) and the Xi(c)'(D) over bar (s)* in molecular state with J(P) = 3/2. According to this result, we strongly suggest the experimental exploration of hidden-charm molecular pentaquarks with double strangeness. Facing such opportunity, obviously the LHCb will have great potential to hunt for them, with the data accumulation at Run III and after High-Luminosity-LHC upgrade.
