论文摘要
我们研究了三体重型B衰变$ \ bar {b}^{0} _ {s} \ rightArrow p \barλk^{ - } $在杆模型的框架内通过Baryonic $λ_{B} $ POL。在计算中,我们需要强耦合常数$ g_ {λ_{λ_{b} b_ {s}λ} $,并研究如果$ g_ {λ_{λ_{b} b_ {s} vistis} = 10.49 \ pm1.57 $与实验结果相符。
We study the three-body baryonic B decay $\bar{B}^{0}_{s}\rightarrow p\barΛ K^{-}$ within the framework of the pole model via the baryonic $Λ_{b}$ pole. In our calculation, we require the strong coupling constant $g_{Λ_{b}B_{s}Λ}$ and investigate if $g_{Λ_{b}B_{s}Λ}=10.49\pm1.57$ is adopted, the branching ratio agrees with the experimental result, reported by the LHCb collaboration.
