具有最小味破坏的Higgs衰变$h\toμτ$

Higgs Decay $h\toμτ$ with Minimal Flavor Violation

Xiao-Gang He, Jusak Tandean, Ya-Juan Zheng

摘要:

我们认为,味道违反希格斯玻色子衰变$h\toμτ$最近在CMS实验的框架内最小的味道违反的初步迹象。具体地说,我们采用标准模型扩展的跷跷板机制,涉及右手中微子和有效的六维运营商满足最小味违反原则的轻子部门。我们发现,它是可能的,以适应CMS的$h\toμτ$信号的解释提供了右手中微子耦合到希格斯玻色子在一些非平凡的方式。我们考虑到其他轻子味违反过程的经验约束,并讨论如何在未来的搜索$μ\to eγ$衰变和$μ\to e$转换的核可能进一步探测轻子味违反希格斯耦合。

英文摘要:

We consider the tentative indication of flavor-violating Higgs boson decay $h\toμτ$ recently reported in the CMS experiment within the framework of minimal flavor violation. Specifically, we adopt the standard model extended with the seesaw mechanism involving right-handed neutrinos plus effective dimension-six operators satisfying the minimal flavor violation principle in the lepton sector. We find that it is possible to accommodate the CMS $h\toμτ$ signal interpretation provided that the right-handed neutrinos couple to the Higgs boson in some nontrivial way. We take into account empirical constraints from other lepton-flavor-violating processes and discuss how future searches for the $μ\to eγ$ decay and $μ\to e$ conversion in nuclei may further probe the lepton-flavor-violating Higgs couplings.
