论文摘要

我们根据$ su(2)_d $ gauge对称性和类似矢量的lept子在其基本表示中提出了一个新颖的Lepton风味和暗物质模型。我们介绍了一个黑暗的$ su(2)_d $ higgs Doublet和一个Higgs Bi-Doubleet,以用于类似矢量的Lepton和Lepton之间的质量混合。结果,产生了Seesaw Lepton群众,并且通过Fermilab E989中指出的是,通过$ SU(2)_D $ GAUGE BOSON和相对沉重的矢量般的Lepton对Muon $ g-2 $有相当大的一环贡献。 $ z $ boson和iSospin中性量规boson $ su(2)_d $之间的树级质量混合在我们的模型帐户中,$ w $ boson质量的变化,与tevatron cdfii一致。最后,我们表明,$ su(2)_d $的ISOSPIN充电仪表成为暗物质的合理候选者,小质量分裂至修改后的$ w $玻色子块,并且有一个可行的参数空间,在其中,对Muon $ g-2 $ and $ w $ w $ boson的质量和$ w $ boson质量的校正和差异很大,并实现了差异。

We propose a novel model for lepton flavor and dark matter based on the $SU(2)_D$ gauge symmetry and vector-like leptons in its fundamental representations. We introduce a dark $SU(2)_D$ Higgs doublet and a Higgs bi-doublet for the mass mixing between the vector-like lepton and the lepton. As a result, the seesaw lepton masses are generated and there are sizable one-loop contributions to the muon $g-2$ via the $SU(2)_D$ gauge bosons and the relatively heavy vector-like lepton, as indicated in Fermilab E989. The tree-level mass mixing between the $Z$ boson and the isospin neutral gauge boson of $SU(2)_D$ in our model accounts for the shift in the $W$ boson mass, being consistent with Tevatron CDFII. Finally, we show that the isospin charged gauge boson of $SU(2)_D$ becomes a plausible candidate for dark matter with a small mass splitting tied up to the modified $W$ boson mass, and there is a viable parameter space where the favored corrections to the muon $g-2$ and the $W$ boson mass and the dark matter constraints are simultaneously fulfilled.
