在超对称跷跷板模型中研究了Higgs交换图对轻子味破坏的μ子-电子转换过程的影响。当tan β较大，中性重Higgs玻色子质量较小时，这种贡献是显著的，此时B（μ N → eN）/B（μ → e γ）的分支比增大.我们还表明，靶原子的转换分支比的依赖性提供了信息的大小的希格斯交换图。
We study the effect of the Higgs-exchange diagram for the lepton flavor violating muon–electron conversion process in nuclei in the supersymmetric see-saw model. The contribution is significant for a large value of tanβ and a small value of a neutral heavy Higgs boson mass, in which case the ratio of the branching ratios of B(μN→eN)/B(μ→eγ) is enhanced. We also show that the target atom dependence of the conversion branching ratio provides information on the size of the Higgs exchange diagram.
