μ子$g-2$与右手中微子SUSY模型中的轻子味破坏

Lepton flavor violations in SUSY models for muon $g-2$ with right-handed neutrinos

Ryo Nagai, Norimi Yokozaki

摘要:

我们考虑超对称(SUSY)模型的μ子$g-2$异常没有味道违反群众在树的水平。该模型可以避免LHC的约束和Stau-Higgs势中的真空稳定性约束。虽然在最小超对称标准模型框架下不能诱导出大的味道破坏过程,但是一旦采用跷跷板模型,就可以诱导出诸如$μ\to e γ$和$μ\to e$转换等大的轻子味道破坏过程.这些LFV过程将在未来的实验中观察到,如MEG-II,彗星和μ 2 e,如果右手中微子比$10^9$ GeV更重的成功leptogenesis的动机。这个结论是有点模型独立,因为希格斯双重需要有大的软超对称性破缺质量,导致味道违反slepton部门通过中微子汤川相互作用。

英文摘要:

We consider supersymmetric (SUSY) models for the muon $g-2$ anomaly without flavor violating masses at the tree-level. The models can avoid LHC constraints and the vacuum stability constraint in the stau-Higgs potential. Although large flavor violating processes are not induced within the framework of minimal SUSY standard model, once we adopt a seesaw model, sizable lepton flavor violating (LFV) processes such as $μ\to e γ$ and $μ\to e$ conversion are induced. These LFV processes will be observed at future experiments such as MEG-II, COMET and Mu2e if right-handed neutrinos are heavier than $10^9$ GeV motivated by the successful leptogenesis. This conclusion is somewhat model independent since Higgs doublets are required to have large soft SUSY breaking masses, leading to flavor violations in a slepton sector via neutrino Yukawa interactions.
