We discuss a model based on a hidden $U{(1)}_X$ gauge symmetry in which neutrino mass is induced at two-loop level by effects of interactions among particles in hidden sector and the Standard Model leptons. Since neutrino mass is suppressed by two-loop, its associate Yukawa couplings can be sizable and it would affect lepton flavor phenomenology. We analyze neutrino mass matrix, lepton flavor violating processes, electron/muon $g-2$ and dark matter annihilation cross section which are induced via interactions among Standard Model leptons and particles in $U{(1)}_X$ hidden sector, and their interactions can be sizable in our scenario. Performing numerical analysis, we show expected ratios for these processes using allowed parameters which can fit the neutrino data and satisfy flavor constraints.

我们讨论一个基于隐藏的模型 $ü{（\mathrm{1个}）}_X$规范对称性，其中中微子质量是通过隐藏扇区中的粒子与标准模型轻子之间的相互作用的影响在两环级上感应的。由于中微子质量被两环抑制，其相关的Yukawa耦合可能相当大，并且会影响轻子味的现象。我们分析了中微子质量矩阵，轻子味道违反过程，电子/介子$G-2$ 和暗物质的dark没截面是通过标准模型轻子与粒子相互作用引起的。 $ü{（\mathrm{1个}）}_X$隐藏的部门，在我们的方案中，它们之间的相互作用可能相当大。执行数值分析，我们使用允许的参数显示了这些过程的期望比率，这些参数可以适合中微子数据并满足风味约束。
