论文摘要
$ W $ -BOSON质量的最近CDF-II测量表明，具有相应的标准模型预测的强度。一旦在低规模的Seesaw机制的背景下解释了活跃的中微子肿块，就可以解决这种张力。我们研究了在同一框架内解释长期的哑光异常磁矩异常的可能性。我们提出了仅针对第二个Lepton生成的标准模型的简化扩展，该模型描述了一个庞大的主动中微子，并为这些异常提供了合并的解决方案。该模型是可ral的，并且在频谱中引入，超出了低尺度seesaw机制的无菌种类，只有一对外来矢量样瘦素，在electroweak对称性下。此外，我们讨论了该模型的扩展到现实的三户家庭案例。
The recent CDF-II measurement of the $W$-boson mass shows a strong tension with the corresponding Standard Model prediction. Once active neutrino masses are explained in the context of the Low-Scale Seesaw mechanisms, this tension can be resolved. We investigate the possibility of explaining the longstanding muon anomalous magnetic moment anomaly within the same frameworks. We present a simplified extension of the Standard Model, accounting only for the second lepton generation, that describes a massive active neutrino and provides a combined solution to these anomalies. The model is renormalisable and introduces in the spectrum, beyond the sterile species of the Low-Scale Seesaw mechanism, only one pair of exotic vector-like leptons, doublets under the electroweak symmetry. We moreover discuss the extension of this model to the realistic three-family case.
