摘要:

我们在一个扩展的镜像费米子模型中研究了单圈诱导的带电轻子味破坏衰变。该模型中的带电轻子扇区具有水平$A_4$对称性和电弱尺度右手中微子。我们证明,对于125 GeV标量$h$有最近的大型强子对撞机的结果${\cal B}(h \to τμ) \sim $ 1%和严格的限制罕见的过程$μ\to e γ$和$τ\to (μ$或$e) γ$从低能实验之间的紧张局势。

英文摘要:

We perform the one-loop induced charged lepton flavor violating decays of the neutral Higgses in an extended mirror fermion model with non-sterile electroweak-scale right-handed neutrinos and a horizontal $A_4$ symmetry in the lepton sector. We demonstrate that for the 125 GeV scalar $h$ there is tension between the recent LHC result ${\cal B}(h \to τμ) \sim $ 1% and the stringent limits on the rare processes $μ\to e γ$ and $τ\to (μ$ or $e) γ$ from low energy experiments.
