Abstract

Motivated by the latest CDF W-mass measurement as well as the muon g2 anomaly and the discrepancies observed in bs+ transitions, we propose an extension of the Standard Model (SM) with the SU(2)L-singlet vector-like fermion partners that are featured by additional U(1) gauge symmetry. The fermion partners have the same SM quantum numbers as of the right-handed SM fermions, and can therefore mix with the latter after the electroweak and the U(1) symmetry breaking. As a result, desirable loop-level corrections to the (g2)μ, the W-boson mass mW and the Wilson coefficient C9 in bsμ+μ transitions can be obtained. The final allowed parameter space is also consistent with the constraints from the Zμ+μ decay, the neutrino trident production and the LHC direct searches for the vector-like quarks and leptons.

将 CDF W 质量偏移与介子 g - 2 和 b → sℓ+ℓ- 转变相关联
受最新的 CDF - 质量测量以及μ介子反常现象和在跃迁中观察到的差异的启发,我们提出了标准模型(SM)的一种扩展,即具有额外规对称性的小矢量费米子伙伴。这些费米子伙伴的量子数与 SM 右手费米子的量子数相同,因此可以在电弱和对称破缺之后与后者混合。因此,可以获得对Ⅳ-玻色子质量和转换中威尔逊系数的理想环级修正。最终允许的参数空间也与衰变、中微子三叉戟产生以及大型强子对撞机直接搜索类矢量夸克和轻子的约束相一致。

期刊介绍: Nuclear Physics B focuses on the domain of high energy physics, quantum field theory, statistical systems, and mathematical physics, and includes four main sections: high energy physics - phenomenology, high energy physics - theory, high energy physics - experiment, and quantum field theory, statistical systems, and mathematical physics. The emphasis is on original research papers (Frontiers Articles or Full Length Articles), but Review Articles are also welcome.
