Prediction of hidden-charm pentaquarks with double strangeness

Abstract

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 ${\Xi }_c^{(\prime ,\ast )}$ and an $S$-wave anti-charmed-strange meson ${\bar{D}}_s^{(\ast )}$. 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 ${\Xi }_c^{\ast }{\bar{D}}_s^{\ast }$ molecular state with $J^P=5/2^{-}$ and the ${\Xi }_c^{\prime }{\bar{D}}_s^{\ast }$ 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.
