在推广了反跷跷板机制的标准模型（SM）框架下，分析了轻子味破坏过程μ-e转换，li→ljγ和li→3lj，作为参数化轻中微子混合子矩阵偏离幺正的函数.在较宽的范围内，对μ-e转化率和μ→eγ分支比的预测与实验上限或未来的实验灵敏度相当一致。对于大尺度的轻子味过程，对其他轻子味过程分支比的预测也可以达到实验上限或未来的实验灵敏度。的值取决于马约拉纳质量项Mμ的行列式。最后，在实验中寻找轻子味破坏过程为我们寻找中微子质量的跷跷板性质提供了更多的机会。
We analyze the lepton flavor violation processes μ-e conversion, li→ljγ and li→3lj in framework of the Standard Model (SM) extended with inverse seesaw mechanism, as a function of that parametrizes the departure from unitary of the light neutrino mixing sub-matrix . In a wide range of , the predictions on the μ-e conversion rates and the branching ratio of μ→eγ are sizeable to be compatible with the experimental upper limits or future experimental sensitivities. For large scale of , the predictions on branching ratios of other lepton flavor processes can also reach the experimental upper limits or future experimental sensitivities. The value of depends on the determinant of the Majorana mass term Mμ. Finally, searching for lepton flavor violation processes in experiment provides us more opportunities for the searches of seesaw nature of the neutrino masses.
