用μ ~* 到反μ ~* 转换实验探测双电荷Higgs粒子

Probing the doubly-charged Higgs with Muonium to Antimuonium Conversion Experiment

Chengcheng Han, Da Huang, Jian Tang, Yu Zhang

摘要:

自发的μ ~-到反μ ~-的转换是有趣的荷电轻子味破坏过程之一。MACE是探索这种现象的下一代实验。在具有三重态Higgs产生中微子质量的模型中,如II型跷跷板及其变体,这一过程可以由其中包含的双电荷Higgs引起。本文研究了MACE通过μ ~--antiuonium跃迁探测这些模型的前景。在考虑了$μ^+ \rightarrow e^+ γ$和$μ^+ \rightarrow e^+ e^- e^+$的局限性后,我们发现MACE可以探测到LHC和其他味实验所不能探测到的双电荷Higgs粒子的参数空间。

英文摘要:

The spontaneous muonium-to-antimuonium conversion is one of the interesting charged lepton flavor violation processes. MACE is the next generation experiment to probe such a phenomenon. In models with a triplet Higgs to generate neutrino masses, such as Type-II seesaw and its variant, this process can be induced by the doubly-charged Higgs contained in it. In this article, we study the prospect of MACE to probe these models via the muonium-to-antimuonium transitions. After considering the limits from $μ^+ \rightarrow e^+ γ$ and $μ^+ \rightarrow e^+ e^- e^+$, we find that MACE could probe a parameter space for the doubly-charged Higgs which is beyond the reach of LHC and other flavor experiments.
