论文摘要
最近报道了$ W $玻色子质量的新CDF测量的动机，该测量与标准模型（SM）预测相比明确说明了较大的偏差。在本文中，我们研究了对$ m_w $的两种双重双重模型（2HDM）的贡献及其现象学含义，在此情况下，大量的CP-EVE-EH $被确定为观察到的Higgs Boson，质量为$ 125 $ GEV。考虑到理论和所有可用的实验约束以及新的CDF测量，我们证明了2HDM参数空间可以提供较大的校正，该校正可预测接近新的CDF $ M_W $测量的W质量。发现排除了$ m_ {h \ pm} = m_a $，并且在所有其他状态下，带电的希格斯玻色的分裂是正。我们还讨论了有效混合角$ \ sin^2θ_ {\ text {eff}} $的后果以及对带电的希格斯和CP-ODD衰变的现象学意义。
Motivated by the new CDF measurement of the $W$ boson mass reported recently which clearly illustrates a large deviation compared to the Standard Model (SM) prediction. In the present paper, we study the Two-Higgs Doublet Model (2HDM) contributions to $M_W$ and its phenomenological implications in the case where the heavy CP-even $H$ is identified as the observed Higgs boson with a mass of $125$ GeV. Taking into account theoretical and all the available experimental constraints as well as the new CDF measurement, we demonstrate that the 2HDM parameter space can provide a large correction which predicts the W mass close to the new CDF $M_W$ measurement. It is found that $M_{H\pm}=M_A$ is excluded and the splitting of the charged Higgs boson with all other states is positive. We also discuss the consequence on the effective mixing angle $\sin^2θ_{\text{eff}}$ as well as the phenomenological implications on the charged Higgs and CP-odd decays.
