解决辐射中微子质量、暗物质、$(g-2)_μ$和$H_0$张力的隐藏规范$U(1)$

摘要:

我们提出了一个具有隐藏$U(1)$规范对称性的辐射跷跷板模型。为了有反常抵消,我们需要引入几个新的费米子,有助于μ子反常磁偶极矩$(g-2)_μ$以及解释中微子振荡数据。我们还考虑了同时与$(g-2)_μ$和中微子质量矩阵相关的费米暗物质候选者。我们在我们的输入参数满足几个限制允许的区域。最后,我们还简要地讨论了通过中微子自相互作用介导的一个更轻的隐藏的规范玻色子不破坏我们的模型的解决方案的哈勃紧张的可能性。

英文摘要:

We propose a radiative seesaw model with a hidden $U(1)$ gauge symmetry. In order to have anomaly cancellations, we need to introduce several new fermions that contribute to muon anomalous magnetic dipole moment $(g-2)_μ$ as well as explain the neutrino oscillation data. We also consider a fermionic dark matter candidate that correlates with $(g-2)_μ$ and neutrino mass matrix at the same time. We show allowed regions in our input parameters satisfying several constraints. Finally, we also briefly discuss the possibility of the resolution of the Hubble tension via neutrino self-interactions mediated by a lighter hidden gauge boson without spoiling our model.
