论文摘要
我们根据CDF协作对$ W $玻色子质量的精确测量，分析了两个Higgs Doublet模型（2HDM）的框架中带电和中性希格斯玻色子的质谱。我们认为，在希格斯（Higgs）的明确CP违规的基础上，我们考虑了最一般的2HDM潜力，其中包含三个CP混合中性的中性质量特征，$ H_1 $，$ H_2 $和$ H_3 $，带有$ M_ {H_1} \ leq m_ {H_2} \ leq m_ {h_2} \ leq m__3} $。 $ w $玻色子质量的高精度CDF测量的特征是$ t $参数的较大正值。通过确定最浅的中性希格斯玻色子$ h_1 $，就像在LHC上发现的那样，我们发现有必要在被带电的Higgs boson $ h^\ pm $和第二个重的中性中性$ H_2 $之间进行质量分配，以适应其$ T $ the $ t $ parameter的$ H_2 $，以适应其$ t $ parameter的$ 0 $ 0 $ 0 $ 0。通过将质量分配在$ h^\ pm $和$ h_2 $之间的质量与扰动单位性的理论约束以及Higgs从下面的界限结合在一起，我们实施了对重型Higgs玻色子的全面分析，以考虑到偏置限制的偏差和质量分配的差异和$ H__3 $和$ h__3 $和$ h__3 $ h_3 $和$ h__3 $。我们根据$ t $参数的变化进一步分析了重态质谱的行为。最后，专注于重质量区域$ m \ equiv（m_ {h_2}+m_ {h^\ pm}）/2 \ gsim 500 $ gev，我们发现$ m \ gg m_ {h_1} \ sim |Δ|δ|δ|δ|δ|δ|带有$δ\ equiv m_ {h_2} -m_ {h^\ pm} $和$Δ\ equiv m_ {
We analyze the mass spectrum of the charged and neutral Higgs bosons in the framework of two Higgs doublet model (2HDM) in the light of the precision measurement of the $W$ boson mass by the CDF collaboration. We have considered the most general 2HDM potential with explicit CP violation in the Higgs basis which contains the three CP-mixed neutral mass eigenstates $H_1$, $H_2$, and $H_3$ with $M_{H_1}\leq M_{H_2}\leq M_{H_3}$. The high-precision CDF measurement of the $W$ boson mass is characterized by the large positive value of the $T$ parameter. By identifying the lightest neutral Higgs boson $H_1$ as the SM-like one discovered at the LHC, we find that it is necessary to have the mass splitting between the charged Higgs boson $H^\pm$ and the second heaviest neutral one $H_2$ to accommodate the sizable positive deviation of the $T$ parameter from its SM value of $0$. By combining the mass splitting between $H^\pm$ and $H_2$ with the theoretical constraints from the perturbative unitarity and for the Higgs potential to be bounded from below, we implement comprehensive analysis of the mass spectrum of the heavy Higgs bosons taking account of the effects of deviation from the alignment limit and also the mass splitting between $H_3$ and $H_2$. We further analyze the behavior of the heavy-Higgs mass spectrum according to the variation of the $T$ parameter. Finally, concentrating on the heavy mass region $M\equiv (M_{H_2}+M_{H^\pm})/2\gsim 500$ GeV in which we find a mass hierarchy of $M\gg M_{H_1}\sim |Δ| \gsim δ$ with $Δ\equiv M_{H_2}-M_{H^\pm}$ and $δ\equiv M_{H_3}-M_{H_2}$, we discuss some benchmarking scenarios for the searches of heavy Higgs bosons at future colliders such as the high luminosity option of the LHC and a 100 TeV hadron collider.
