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.

Automated summary

Inspired by recent evidence reported by LHCb, this investigation explores hidden-charm molecular pentaquarks with double strangeness, suggesting the existence of two types and strongly recommending experimental exploration. The LHCb has great potential to discover these pentaquarks in the future data accumulation.
