论文摘要
Cabibbo角异常是第一行CKM单位性的明显赤字，可以通过瘦素标准模型扩展来解决，从而为费米常数产生新的贡献并影响CKM元素$ v_ {ud} $的确定。我们专注于具有此属性的简化模型，包括由矢量般的Leptons扩展的标准模型，由单个带电的标量单元或瘦素$ z'$ boson扩展。
The Cabibbo Angle Anomaly, an apparent deficit in first-row CKM unitarity, can be addressed by leptophilic Standard Model extensions that generate new contributions to the Fermi constant and affect the determination of the CKM element $V_{ud}$. We focus on simplified models with this property, including the Standard Model extended by vectorlike leptons, by the singly charged scalar singlet, or by a leptophilic $Z'$ boson.
