论文摘要
我们表明，在两个Higgs Doublet模型中，II类型II扩展了矢量般的Leptons，从沉重的中性和充电Higgs Bosons到MUON的异常磁矩，同时具有手性增强，从新的Leptons和$ \ tan^2β$ \ tan^2β$增强了couplings from couplings higsons of higsons ossons sosons。假设新的Yukawa耦合的中等值（不超过一个耦合）可能仍然扰动非常高的能量尺度，那么即使使用6.5 TEV Leptons或20 Tev Higgs玻色子，也可以在一个标准偏差中解释Muon $ G-2 $的测量值。允许在扰动性极限附近进行新的耦合，这些质量范围扩展到Higgs玻色子的瘦素和190 TEV的45个TEV。尽管新物理学的规模很高，但仍可以在计划中的未来小组中彻底探测这种情况。
We show that in a two Higgs doublet model type-II extended by vectorlike leptons the contributions from heavy neutral and charged Higgs bosons to the anomalous magnetic moment of the muon simultaneously feature chiral enhancement from masses of new leptons and $\tan^2 β$ enhancement from couplings of Higgs bosons. Assuming moderate values of new Yukawa couplings, not exceeding one, that can remain perturbative to very high energy scales, the measured value of muon $g-2$ can be explained within one standard deviation even with 6.5 TeV leptons or 20 TeV Higgs bosons. Allowing new couplings near the perturbativity limit, these mass ranges extend to 45 TeV for leptons and 190 TeV for Higgs bosons. In spite of the high scale of new physics this scenario can be completely probed at planned future colliders.
