论文摘要
我们表明，标准模型中最简单的扩展之一，第二个Higgs Doublet与深色扇区单线标量相结合时，使我们能够：$ i）解释液体闪烁剂中微子探测器（LSND）和Miniboone（MB）的长期异常，同时保持了与Karmen相同的过程，同时又与Karmen $ ii相同，同时$ i II，$ i II。行业和$ iii）$舒适地说明了穆恩$ g-2 $的观察值。三个单元中微子可以通过I型I类型的观察到的中微子质谱差异来理解，其中两个较轻的状态参与了LSND和MB的相互作用。在两个实验中，我们都可以很好地拟合能量和角度分布。我们解释了此处介绍的解决方案的特征，并讨论了我们的模型必须满足的约束。我们还提到了对其颗粒含量的未来测试的前景。
We show that one of the simplest extensions of the Standard Model, the addition of a second Higgs doublet, when combined with a dark sector singlet scalar, allows us to: $i)$ explain the long-standing anomalies in the Liquid Scintillator Neutrino Detector (LSND) and MiniBooNE (MB) while maintaining compatibility with the null result from KARMEN, $ii)$ obtain, in the process, a portal to the dark sector, and $iii)$ comfortably account for the observed value of the muon $g-2$. Three singlet neutrinos allow for an understanding of observed neutrino mass-squared differences via a Type I seesaw, with two of the lighter states participating in the interaction in both LSND and MB. We obtain very good fits to energy and angular distributions in both experiments. We explain features of the solution presented here and discuss the constraints that our model must satisfy. We also mention prospects for future tests of its particle content.
