论文摘要
模块化对称性在中微子和夸克部门无可挑剔。因此，这促使我们提出了一种基于模块化$ A_4 $对称性的Scotogenic模型的变体，以通过辐射机制在单环上实现中微子质量的产生。除了违反Lepton风味的过程$μ\至Eγ$和MUON $ G-2 $异常。最轻的Majorana费米斯可能是潜在的候选暗物质候选物，可以通过适当的模块化重量分配稳定。同一的遗物密度已经计算出惰性标量和新$ u（1）$ gauge玻色体介导的歼灭。
Modular symmetries have been impeccable in neutrino and quark sectors. This motivated us, therefore, to propose a variant of scotogenic model based on modular $A_4$ symmetry to realize the neutrino mass generation at one-loop level through radiative mechanism. Alongside, the lepton flavour violating process $μ\to e γ$ and the muon $g-2$ anomaly are also addressed. The lightest Majorana fermions turn out to be potential dark matter candidates, made stable by suitable assignment of modular weights. The relic density of the same has been computed with annihilations mediated by inert scalars and new $U(1)$ gauge boson.
