论文摘要
我们执行$ b \ rightarrow c \ bar {c} s（d）$ baryon Antitriplet成员的$ b \ rightarrow c \ bar {c} s（c} s（d）的一般su（3）$ _ f $分析。在几个合理的假设下，我们找到了$ \ left \ vert \ mathcal {a}（ξ_b^0 \rightarrowλs）/ \ Mathcal {a}（ξ_b^0 \ rightArrowξ^0 s） v_ {cd} /（v_ {cb}^* v_ {cs}）\ right \ vert $和$ \ left \ left \ vert \ mathcal {a}（λ_b\ rightArrowσ^0 s） / \ mathcal {a} LHCB最近针对$ s = j/ψ$探讨了这两个关系。前者同意测量，而对于后者，我们的预测位于LHCB设置的上限。
We perform a general SU(3)$_F$ analysis of $b\rightarrow c\bar{c}s(d)$ decays of members of the beauty baryon antitriplet to a member of the light baryon octet and a singlet. Under several reasonable assumptions we found $\left\vert \mathcal{A}(Ξ_b^0\rightarrow ΛS)/ \mathcal{A}(Ξ_b^0\rightarrow Ξ^0 S)\right\vert\approx 1/\sqrt{6}\, \left\vert V_{cb}^* V_{cd} / (V_{cb}^* V_{cs})\right\vert$ and $\left\vert\mathcal{A}(Λ_b\rightarrow Σ^0 S)/\mathcal{A}(Λ_b\rightarrow ΛS)\right\vert \sim 0.02$. These two relations have been recently probed by LHCb for the case of $S=J/ψ$. The former agrees with the measurement, while for the latter our prediction lies close to the upper bound set by LHCb.
