μ子反常的完全类矢量第四族和新的U(1)$^\prime$

Complete vectorlike fourth family and new U(1)$^\prime$ for muon anomalies

Junichiro Kawamura

摘要:

本文介绍了一个模型来解释最近的μ子反常磁矩和罕见的半轻子$B$介子衰变的反常现象。标准模型被一个$U(1)^\prime$规范对称性和一个在规范对称性下类矢量的完整的第四族费米子所扩展。我们发现参数点,可以解释与其他观测值一致的异常。然后,我们提出了一个有趣的可能性,有四个μ子或更多的信号从矢量轻子对生产。

英文摘要:

I introduce a model to explain the recent anomalies in the muon anomalous magnetic moment and the rare semi-leptonic $B$ meson decays. The Standard Model is extended by a $U(1)^\prime$ gauge symmetry and a complete fourth family fermions which are vector-like under the gauge symmetry. We found parameter points which can explain the anomalies consistently with the other observables. We then propose an interesting possibility to have signals with four muons or more from vector-like lepton pair production.
