论文摘要
我们介绍了CDF II上$ W $ BOSON最近在两-higgs-doublet模型(2HDM)上测量的含义。在分析中,我们施加了理论界限,例如真空稳定性和扰动单位性以及几个实验性约束。此外,我们考虑了$ \ sin^2θ_w(m_z)_ {\ rm \ bar {ms}} $在CDF $ W $ -BOSON质量上的测量值,以调查$ S $和$ t $参数的确定如何确定。我们根据在LHC上观察到的Higgs玻色子是$ CP $ - $ CP $ -EVEN中性的Higgs Bosons的较轻或更重的情况,我们探索了两种可能的情况。使用结果,我们显示了如何约束参数空间,并将其与基于$ M_W $的PDG平均值进行比较。此外,我们探索了Electroweak Precision可观察物的现象学后果,这些后果可能会在2HDM的预测中受到$ M_W $的影响,以及从未来的圆形Lepton Collider的未来测量中预期的参数空间减少。
We present the implications of the recent measurement of $W$ boson at CDF II on the two-Higgs-doublet model (2HDM). In the analysis, we impose theoretical bounds such as vacuum stability and perturbative unitarity, and several experimental constraints. In addition, we take into account the measurement of $\sin^2θ_W(m_Z)_{\rm \bar{MS}}$ on top of the CDF $W$-boson mass to investigate how the $S$ and $T$ parameters are determined. We explore two possible scenarios depending on whether the Higgs boson observed at the LHC is the lighter or heavier of $CP$-even neutral Higgs bosons for 2HDM type I and II. Using the results, we show how the parameter space is constrained, and compare it with the one based on the PDG average of $m_W$. Furthermore, we explore phenomenological consequences of electroweak precision observables that can be affected by $m_W$ within the predictions of the 2HDM, and the reduction in parameter space expected from future measurements at the Future Circular Lepton Collider.
