论文摘要
我们研究了基于夸克和看不见的颗粒之间的模型无关的lagrangian，研究了$χ$的底部baryon衰减中$χ$的不可见的主要fermions。从从实验中提取的耦合常数的边界中，我们研究了$λ_b\toλχ$，$λ_b\toλ的衰减比率，$ξ_b^{0（ - ）} \ to了ξ^{0（ - ）} um $Ξ_b^{0}\to Σ^{0} χχ$, and $Ξ_b^{0}\to Λχχ$, which can be as large as $6.3,~9.2,~5.7,~5.8,~2.7$, and $1.0\times10^{-5}$ for $m_χ=2$ GeV, respectively.这些衰减中的一些可以通过未来的实验搜索（例如Belle II）访问。
We study the invisible Majorana fermions of $χ$ in bottomed baryon decays with flavor-changing neutral currents (FCNCs) based on the model-independent effective Lagrangian between the quarks and invisible particles. From the bounds of the coupling constants extracted from the experiments, we examine the decay branching ratios of $Λ_b\toΛχχ$, $Ξ_b^{0(-)}\toΞ^{0(-)}χχ$, $Λ_b\to n χχ$, $Ξ_b^{-}\to Σ^{-} χχ$, $Ξ_b^{0}\to Σ^{0} χχ$, and $Ξ_b^{0}\to Λχχ$, which can be as large as $6.3,~9.2,~5.7,~5.8,~2.7$, and $1.0\times10^{-5}$ for $m_χ=2$ GeV, respectively. Some of these decays are accessible to the future experimental searches, such as Belle II.
