论文摘要
我们研究了带有$ A_4 $离散对称性的流行中微子质量模型中带电的Lepton风味违规行为。这种对称性需要该模型中存在多个HigGS双线仪，并且还决定了模型附加中性标量的Yukawa耦合的风味。这样的耦合导致中性介子，顶级夸克和$τ$ Lepton的衰变变成了树层的不同口味的带电瘦素。模型的$ A_4 $对称性导致这些衰变中的某些特征签名。我们讨论了这些签名，并预测了最有利的充电Lepton风味模式的费率。
We study the charged lepton flavour violation in a popular neutrino mass model with $A_4$ discrete symmetry. This symmetry requires the presence of multiple Higgs doublets in the model and it also dictates the flavour violating Yukawa couplings of the additional neutral scalars of the model. Such couplings lead to the decays of the neutral mesons, the top quark and the $τ$ lepton into charged leptons of different flavours at tree level. The $A_4$ symmetry of the model leads to certain characteristic signatures in these decays. We discuss these signatures and predict the rates for the most favourable charged lepton flavour violating modes.
