论文摘要
我们分析了扩展的2HDM理论在夸克质量和混合，Electroweak Precision测试，充电Lepton风味（CLFV）衰减，中微子三叉戟生产，B Meson，B Meson，$ G-2 $ MUON和W ANOMALIES中的含义。在这项工作中考虑的扩展的2HDM理论中，SM量规对称性由局部$ u（1）^{\ prime} $对称性扩大，而其标量和费米子扇区分别通过纳入量表单重标量表和vectorlike like fermions的包含来增强。在该模型的框架内，我们确定$ z^{\ prime} $量规boson质量的允许范围，与中微子三叉戟生产所产生的约束，$ r_ {k^{*}} $ anomaly，$ b_ {s} $ meson iScillation。我们得出结论$ r_ {k^{*}} $，muon $ g-2 $异常在所有约束下都不能同一新物理学同时解释。除此之外，我们发现新的物理源，$ z^{\ prime} $和非SM标量无法通过标量电势连接。此外，我们发现所考虑的模型可以成功遵守斜面$ t，s，u $参数以及$ W $质量和$ g-2 $ muon异常的约束。特别是我们发现，MUON $ G-2 $异常，其主要贡献是由一个环级标量交换产生的，可以在$2σ$实验允许的范围内成功容纳。
We analyze the implications of an extended 2HDM theory in quark masses and mixings, electroweak precision tests, charged lepton flavor violating (CLFV) decays, neutrino trident production, B meson, $g-2$ muon and W anomalies. In the extended 2HDM theory considered in this work, the SM gauge symmetry is enlarged by the local $U(1)^{\prime}$ symmetry, whereas its scalar and fermion sectors are augmented by the inclusion of a gauge singlet scalar and vectorlike fermions, respectively. Within the framework of this model, we determine the allowed ranges of the $Z^{\prime}$ gauge boson mass consistent with the constraints arising from neutrino trident production, $R_{K^{*}}$ anomaly, $B_{s}$ meson oscillation. We conclude the $R_{K^{*}}$ and muon $g-2$ anomalies cannot be simultaneously explained by the same new physics under all the constraints. Besides that, we found that the new physics sources, the $Z^{\prime}$ and non SM scalars cannot be connected via the scalar potential. Furthermore, we have found that the model under consideration can successfully comply with the constraints arising from oblique $T,S,U$ parameters as well as with the $W$ mass and $g-2$ muon anomalies. In particular we found that the muon $g-2$ anomaly, whose dominant contribution arises from the one loop level scalar exchange, can be successfully accommodated within the $2σ$ experimentally allowed range.
