论文摘要
我们讨论了一个黑暗部门的模型，其中，带电的瘦素和中微子的质量较小可以通过黑暗扇区中颗粒介导的一环效应来解释。这些新粒子（包括暗物质候选者）也有助于用于带电的瘦素的$（g-2）$表示异常的磁偶极力矩。我们表明，我们的模型可以解释MUON $（G-2）$异常，并在违反了带电瘦素的衰减的限制下观察到中微子振荡。我们说明，标量暗物质的场景受到LHC的直接搜索的高度限制，而使用费米的暗物质则可以考虑具有100 GEV顺序的暗标量。可以通过精确测量Yukawa耦合以及在未来的电子峰乘积上直接产生深色标量玻色子来测试我们的方案。
We discuss a model with a dark sector, in which smallness of mass for charged leptons and neutrinos can naturally be explained by one-loop effects mediated by particles in the dark sector. These new particles, including dark matter candidates, also contribute to the anomalous magnetic dipole moment, denoted by $(g-2)$, for charged leptons. We show that our model can explain the muon $(g-2)$ anomaly and observed neutrino oscillations under the constraints from lepton flavor violating decays of charged leptons. We illustrate that the scenario with scalar dark matter is highly constrained by direct searches at the LHC, while that with fermionic dark matter allows for considering dark scalars with masses of order 100 GeV. Our scenario can be tested by a precise measurement of the muon Yukawa coupling as well as the direct production of dark scalar bosons at future electron-positron colliders.
