论文摘要

我们考虑使用类似矢量的Lepton和本地$ u(1)'$对称性的标准模型(SM)的简单扩展,这是由于最近在Muon $ G-2 $和$ W $ w $ boson Mass中的实验异常的动机。 $ u(1)'$对称性被深色希格斯标量和第二个希格斯双重的VEV自发打破,从而产生了Muon和类似矢量的Lepton之间的混合。结果,我们同时获得了Muon $ G-2 $和$ W $ boson质量的理想更正,这主要是由于分别为矢量般的Lepton和第二个Higgs Doublet的$ z'$量规交互。我们还与$ z $玻色子衰变宽度,希格斯耦合和Dilepton边界讨论了该模型的一致性。

We consider a simple extension of the Standard Model (SM) with a vector-like lepton and a local $U(1)'$ symmetry, motivated by the recent experimental anomalies in the muon $g-2$ and the $W$ boson mass. The $U(1)'$ symmetry is spontaneously broken by the VEVs of the dark Higgs scalar and the second Higgs doublet, giving rise to the mixing between the muon and the vector-like lepton. As a result, we obtain the desirable corrections to the muon $g-2$ and the $W$ boson mass simultaneously, dominantly due to the $Z'$ gauge interactions for the vector-like lepton and the second Higgs doublet, respectively. We also discuss the consistency of the model with the $Z$ boson decay width, the Higgs couplings and the dilepton bounds.
