论文摘要
CDF协作对$ W $玻色子质量的最新测量为MUON异常磁矩（$ΔA_μ$ $ $ $ΔA_μ$）的长期差异增加了异常。尽管在两-higgs-doublet模型中的Type-X通过轻型伪库$ a $为$ΔA_μ$提供了有吸引力的解决方案，但该模型面临着异国情调的higgs衰减，$ h \ to aa $和$τ$和$ z $衰减中的Lepton Flavor Commitality Data。为了节省模型，我们建议光伪库s鼠恐惧症。通过对整个参数空间的随机扫描，我们对Higgs-Phobic Type-X进行了比较研究，并没有CDF $ M_W $测量，分别称为CDF和PDG病例。两种情况都可以解释两个异常以及所有其他约束，但最终允许的参数空间有显着差异。例如，只有在PDG情况下，只允许一个几乎变性的新希格斯玻色子质量的小区域。还通过对$ 10^5〜 {\ rm GEV} $（$ 10^7〜 {\ rm Gev} $）在CDF（PDG）案例中的$ 10^5〜 {\ rm GEV} $（$ 10^5〜 {\ rm gev} $）中研究了模型的截止量表。由于主要的衰减模式为$ a \至ττ$，$ h \ to z a $，而$ h^\ pm \ to to w^\ pm a $在大多数可行的参数空间中，我们建议$4τ+vv'$ state作为LHC的金色发现通道。
The recent measurement of the $W$ boson mass by the CDF collaboration adds an anomaly to the long-standing discrepancy in the muon anomalous magnetic moment, $Δa_μ$. Although type-X in the two-Higgs-doublet model provides an attractive solution to $Δa_μ$ through a light pseudoscalar $A$, the model confronts the exotic Higgs decays of $h\to AA$ and the lepton flavor universality data in the $τ$ and $Z$ decays. To save the model, we propose that the light pseudoscalar be Higgs-phobic. Through the random scanning over the entire parameter space, we perform a comparative study of the Higgs-phobic type-X with and without the CDF $m_W$ measurement, called the CDF and PDG cases respectively. Both cases can explain the two anomalies as well as all the other constraints but have significant differences in the finally allowed parameter space. For example, a small region with almost degenerate masses of new Higgs bosons around 100 GeV is allowed only in the PDG case. The cutoff scale of the model is also studied via the analysis of renormalization group equations, which reaches up to $10^5~{\rm GeV}$ ($10^7~{\rm GeV}$) in the CDF (PDG) case. Since the dominant decay modes are $A\to ττ$, $H \to Z A$, and $H^\pm\to W^\pm A$ in most of the viable parameter space, we propose the $4τ+VV'$ states as the golden discovery channel at the LHC.
