味变的Majoron与轻子的相互作用

Flavor-changing Majoron interactions with leptons

Yu Cheng, Cheng-Wei Chiang, Xiao-Gang He, Jin Sun

摘要:

当标准模型的希格斯扇区被扩展为一个复杂的单线态,它自发地打破了整体轻子数对称性,一个无质量的戈德斯通玻色子称为Majoron J出现了。除了通过混合增加希格斯粒子的不可见衰变外,马约朗通常还可以与费米子发生变味的相互作用。我们发现,III型跷跷板模型提出了这样有趣的性质与带电轻子和中微子。这为寻找马约伦开辟了新的渠道。我们利用μ介子-反μ介子振荡和变味中微子与带电轻子衰变的实验数据对耦合进行了约束。作为一种新的方法来揭示这些相互作用的手征性质,我们提出了一个实验上可测量的偏振不对称的味道改变l到l' J衰变。

英文摘要:

When the Standard Model Higgs sector is extended with a complex singlet that breaks global lepton number symmetry spontaneously, a massless Goldstone boson called the Majoron J arises. In addition to increasing Higgs invisible decay through mixing, the Majoron can generally have flavor-changing interactions with fermions. We find that type-III seesaw model poses such interesting properties with both charged leptons and neutrinos. This opens up new channels to search for the Majoron. We use the experimental data such as muonium-anti-muonium oscillation and flavor-changing neutrino and charged lepton decays to put constraints on the couplings. As a novel way to reveal the chiral properties of these interactions, we propose an experimentally measurable polarization asymmetry of flavor-changing l to l' J decays.
