We propose a model with radiatively induced neutrino mass at two-loop level, applying modular $A_4$ symmetry. The neutrino mass matrix is formulated where the structure of associated couplings is restricted by the symmetry. Then we show several predictions in the lepton sector, satisfying lepton flavor violations as well as neutrino oscillation data. We also discuss muon anomalous magnetic moment and briefly comment on dark matter candidate.

具有模块A ₄对称性的两环感应中微子质量模型

我们提出了一个在两个回路水平上具有辐射诱发的中微子质量的模型，并应用了模块化 ${\mathrm{一个}}_4$对称。制定中微子质量矩阵，其中相关联的耦合结构受对称性限制。然后，我们在轻子领域显示了一些预测，满足了轻子风味违规以及中微子振荡数据的需求。我们还将讨论μ子异常磁矩，并简要评论暗物质候选物。
