论文摘要
CDF II协作对$ W $ - 大质量的最新精确度量表明了超出标准模型的新物理。另一方面，长期以来的MUON $ G-2 $异常的解决方案也要求其他动态。在这项工作中，我们在最小的II Seesaw模型的扩展中适应了上述两个异常。也就是说，最小的II型模型通过额外的双带电标量和向量私体增强。虽然矢量lept子的手性叉可以预测MUON $ G-2 $的观察值，但最近报道的$ W $ - 质量的值也可以通过模型的倾斜参数同时实现。此外，我们进一步表明，允许同时解决两个异常的参数区域符合中微子质量数据，违反Lepton风味和Electroweak真空稳定性，直到Planck量表。
The recent precise measurement of the $W$-mass by the CDF II collaboration is indicative of new physics beyond the Standard Model. On the other hand, a resolution of the longstanding muon $g-2$ anomaly also calls for additional dynamics. In this work, we accommodate the two aforementioned anomalies in an extension of the minimal Type-II seesaw model. That is, the minimal Type-II model is augmented with an additional doubly charged scalar and vector leptons. While a chirality-flip of the vector leptons can predict the observed value of muon $g-2$, the value of the recently reported $W$-mass can also be simultaneously achieved through the oblique parameters of the model. In addition, we further show that the parameter region allowing for the simultaneous resolution of the two anomalies complies with the neutrino mass data, lepton flavour violation and electroweak vacuum stability up to the Planck scale.
