摘要:

我们考虑一个简单的扩展的标准模型(SM)的一个复杂的标量二重态和一个单线态以及三个不育中微子。不育中微子与SM中微子混合产生三个与振荡数据一致的轻中微子态和三个重不育态。最轻的无菌中微子的寿命比宇宙的年龄长,可以提供正确的暗物质遗迹丰度。利用质量为~ $\sim\mathcal{O}(100)$ ~MeV的光标量与无菌中微子的树级变味相互作用,我们可以同时解释μ子和电子的反常磁矩、KOTO反常事件和MiniBooNE超数。

英文摘要:

We consider a simple extension of the Standard Model (SM) by a complex scalar doublet and a singlet along with three sterile neutrinos. The sterile neutrinos mix with the SM neutrinos to produce three light neutrino states consistent with the oscillation data and three heavy sterile states. The lightest sterile neutrino has lifetime longer than the age of the Universe and can provide correct dark matter relic abundance. Utilizing tree-level flavor changing interactions of a light scalar with mass~$\sim\mathcal{O}(100)$~MeV along with sterile neutrinos, we can explain the anomalous magnetic moments of both muon and electron, KOTO anomalous events and the MiniBooNE excess simultaneously.
