我们考虑了一种解释CDF II W玻色子质量异常的混合规范对称,其中右手费米子带电。研究发现,在避免其他实验约束的同时,它更倾向于适应这种异常。在这种情况下,我们需要额外的带电轻子来抵消量子异常,而SM带电轻子通过与额外的轻子相互作用获得质量。这些相互作用也会引起介子和轻子风味的违反。我们讨论了μ子,可能的风味约束,通过反跷跷板机制产生的中微子质量,以及关于参数空间产生的对撞机物理,解释了玻色子质量异常。
We consider an explanation of the CDF II W boson mass anomaly bymixing withgauge symmetry under which right-handed fermions are charged. It is found thatis 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 muonand lepton flavor violations. We discuss muon, possible flavor constraints, neutrino mass generation via inverse seesaw mechanism, and collider physics regardingproduction for parameter space explaining theboson mass anomaly.
