论文摘要
我们研究了一个成功的模型，以解释源自Yukawa型相互作用{在超对称理论中的元素异常磁矩}。得益于模块化$ a_4 $风味对称性，禁止任何破坏模型的麻风病风味。我们还研究了包括暗物质（DM）候选者的预测性辐射SEESAW模型。首先，我们构建了满足中微子振荡数据的最低模型，并获得了几个预测，例如Dirac CP和Majorana阶段，即通过$χ^2 $分析的中微子质量。但是，最低模型将无法提供我们有希望的DM候选人。因此，我们最少扩展模型并找到一个良好的DM候选者。在扩展框架中，我们显示了允许的区域以满足MUON异常磁矩和观察到的暗物质的遗物密度，除了对Lepton扇形的预测。
We study a successful model to explain the muon anomalous magnetic moment originating from Yukawa-type interactions {in a supersymmetric theory}. Thanks to a modular $A_4$ flavor symmetry, any lepton flavor violations that spoil the model are forbidden. We also investigate a predictive radiative seesaw model including a dark matter (DM) candidate. At first, we construct the minimum model to satisfy the neutrino oscillation data and obtain several predictions such as Dirac CP and Majorana phases, the neutrino masses through $χ^2$ analysis. However, the minimum model would not provide our promising DM candidate. Thus, we minimally extend the model and find a good DM candidate. In the extended framework, we show the allowed regions to satisfy the muon anomalous magnetic moment and the observed relic density of dark matter in addition to predictions of the lepton sector.
