论文摘要
我们探讨了同时解决CDF协作报告的$ W $ -BOSON质量转移以及在一类左右对称模型中CKM混合矩阵的第一行中的明显偏差。在这些模型中，通过通用的Seesaw机制生成了费米昂的质量，利用了常规费米子的矢量样伙伴。我们找到了两个异常的独特解决方案，其中将夸克与矢量句号（VLQ）的混合解决了CKM Unitarity拼图，而顶级夸克与VLQ合作伙伴的混合则解释了$ W $ boson质量偏移。该设置的有效性测试了HIGGS电位至较高能量的稳定性的测试。我们发现$（5，\，4，\，4）$ TEV的上限分别分别与$ su（2）_r $ $ loguge对称性折断相关的中性标量。这类模型可以通过平均对称性解决强大的CP问题，而无需轴承。
We explore the possibility of resolving simultaneously the $W$-boson mass shift reported by the CDF collaboration and the apparent deviation from unitarity in the first row of the CKM mixing matrix in a class of left-right symmetric models. The fermion masses are generated in these models through a universal seesaw mechanism, utilizing vector-like partners of the usual fermions. We find a unique solution to the two anomalies where the mixing of the down quark with a vector-like quark (VLQ) resolves the CKM unitarity puzzle, and the mixing of the top quark with a VLQ partner explains the $W$ boson mass shift. The validity of this setup is tested against the stability of the Higgs potential up to higher energies. We find upper bounds of $(5,\,4,\,4)$ TeV on the masses of the down-type VLQ, the top-partner VLQ, and a neutral scalar associated with $SU(2)_R$ gauge symmetry breaking, respectively. This class of models can solve the strong CP problem via parity symmetry without the need for an axion.
