论文摘要
受到LHCB报道的$ p_ {cs}（4459）$的启发，我们继续对具有双重陌生性的隐藏链分子五角夸克进行调查，这些五夸克是由$ s $ s $ s $ -wave charmed charmed charmed charmed baryon $ CC^{（\ prime，*）$ s $ s $ s $ s $ s-s $ scharm， $ \ bar {d} _s^{（*）} $。 $ s $ -D $ d $ WAVE混合效果和耦合的通道效果都在现实的计算中考虑到。一个动力学计算表明，可能存在两种类型的隐藏式链分子五夸克，即双重陌生，即$ξ_{c}^{*}^{*} \ bar d_s^*$分子状态，$ j^p = {5}/{2}/{2}^ - {2}^{ - }^{ - $ coul prient带有$ j^p = {3}/{2}^{ - } $的状态。根据这个结果，我们强烈建议对具有双重陌生性的隐藏链分子五夸克进行实验探索。面对这样的机会，显然，LHCB将有很大的潜力来寻找它们，并且在运行III和高光度LHC升级之后的数据积累。
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 $Ξ_c^{(\prime,*)}$ and an $S$-wave anti-charmed-strange meson $\bar{D}_s^{(*)}$. 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 $Ξ_{c}^{*}\bar D_s^*$ molecular state with $J^P={5}/{2}^{-}$ and the $Ξ_{c}^{\prime}\bar D_s^*$ 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.
