论文摘要
我们考虑对CDF II W BOSOM质量异常的解释，$ Z-Z'$混合与$ u（1）_r $ $量规对称性，在该章中收取了右手费米子。发现$ u（1）_r $首选是瘦恐惧症来适应异常，同时避免其他实验性约束。在这种情况下，我们需要额外的充电瘦素来取消量子异常，而SM带电的Leptons通过与额外的相互作用获得质量。这些相互作用还会引起Muon $ G-2 $和Lepton风味违规。我们讨论了Muon $ G-2 $，可能的风味限制，通过反透视机制产生中微子质量的质量和对撞机物理学，涉及$ z'$生产的参数空间，解释了W BOSON质量异常。
We consider an explanation of CDF II W bosom mass anomaly by $Z-Z'$ mixing with $U(1)_R$ gauge symmetry under which right-handed fermions are charged. It is found that $U(1)_R$ is preferred to be leptophobic to accommodate the anomaly while avoiding other experimental constraints. In such a case we require extra charged leptons to cancel quantum anomalies and the SM charged leptons get masses via interactions with the extra ones. These interactions also induce muon $g-2$ and lepton flavor violations. We discuss muon $g-2$, possible flavor constraints, neutrino mass generation via inverse seesaw mechanism, and collider physics regarding $Z'$ production for parameter space explaining the W boson mass anomaly.
