论文摘要
我们认为Muon $ g-2 $异常的超对称性（SUSY）模型在树一级的情况下违反风味的群众。这些模型可以避免LHC的约束和Stau-Higgs潜力中的真空稳定性约束。尽管在最小的SUSY标准模型的框架内未诱发违反风味的过程，但一旦我们采用了seesaw模型，就会引起诸如$μ\ toeγ$和$μ\ to e $ conversion的相当大的Lepton风味（LFV）过程。如果右手中微子比成功的瘦素发生动机的$ 10^9 $ GEV重，则将在将来的实验中观察到这些LFV过程，例如MEG-II，彗星和MU2E。该结论在某种程度上是独立的，因为需要希格斯双重速度具有较大的软susy breaking肿块，从而通过中微子的育川相互作用导致Slecton部门的风味违规。
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.
