论文摘要
最近，CDF II合作报道说他们正精确地测量了W玻色子质量。测量值与7 $σ$的标准模型（SM）预测偏离。此外，最近对灵恩磁矩的FNAL测量显示出$4.2σ$偏差。为了解决W Boson以及Muon $（G-2）$异常，我们探索了Type-X Type-X Higgs Doublet型号（2HDM）。我们分析了与Muon $（G-2）$，Lepton通用测试和CDF II合作中最近的$ W $ BOSON质量测量的$（m_a，\tanβ）$参数空间。我们发现，$ h \ to aa $分支比率的尺寸可在$ m_h $上限制强大的较低质量。
Recently CDF II Collaboration reported that they measured W boson mass precisely. The measurement is deviated from the Standard Model (SM) Prediction at 7$σ$. Also, the recent FNAL measurement of the muon magnetic moment shows a $4.2σ$ deviation. To resolve the W boson as well as the muon $(g-2)$ anomalies, we explore the type-X two Higgs doublet model (2HDM). We analyze the $(m_A, \tanβ)$ parameter space of the type-X 2HDM consistent with the muon $(g-2)$, lepton universality test and recent $W$ boson mass measurments from the CDF II collaboration. We find that the measurement of the $h\to AA$ branching ratio gives a strong lower mass bound on $m_H$.
