论文摘要
具有扩展的希格斯玻色子扇区的模型对于研究希格斯衰减的electroweak对称性破坏机理至关重要，并与载体玻色子相关的希格斯产量。在两种二键模型的框架内，使用了从实验测量结果获得的两种方案，我们在轻度CP-even Higgs Boson的四效衰减中呈现了临近领先的结果，$ h \ rightarrow 4f $。借助Monte Carlo计划预测4F 3.0，我们计算了$γ=γ_{ew} /\ left的值（γ_{γ_{ew}+γ_{sm} \ right）$和$γ=γ__ Higgs玻色子衰减通道$ h \rightArrowν_μ\OverlineμE\ Overline {ν_e} $，$μ\OVERLINEμE\ OVERLINE {E} $，$ E \ e \ OVERLINE {E}在Higgs Boson的衰减模式下，将QCD校正到EW过程时，我们没有发现显着差异。使用计算机程序Pythia 8.2和Feynhiggs，我们计算了以下值：$σ（vbh）br（h \ rightarrow zz）$和$σ（vbf）br（h \ rightArrow ww）$ vbf生产过程，$σ（ggh）br（h \ rightarrow ww ww ww ww ww ww ww ww ww z z ggh） 13和14 TEV的生产过程与实验数据发现了很好的一致性。
Models with extended Higgs boson sectors are of prime importance for investigating the mechanism of electroweak symmetry breaking for Higgs decays into four fermions and for Higgs-production in association with a vector bosons. In the framework of the Two-Higgs-Doublet Model using two scenarios obtained from the experimental measurements we presented next-to-leading-order results on the four-fermion decays of light CP-even Higgs boson, $h \rightarrow 4f$. With the help of Monte Carlo program Prophecy 4f 3.0, we calculated the values $Γ= Γ_{EW} /\left(Γ_{EW}+Γ_{SM}\right)$ and $Γ= Γ_{EW+QCD} /\left(Γ_{EW+QCD}+Γ_{SM}\right)$ for Higgs boson decay channels $ H \rightarrow ν_μ \overlineμ e \overline{ν_e}$, $μ\overlineμ e \overline{e}$, $e \overline{e} e \overline{e}$. We didn't find significant difference when accounting QCD corrections to EW processes in the decay modes of Higgs boson. Using computer programs Pythia 8.2 and FeynHiggs we calculated the following values: $σ(VBH)BR(H\rightarrow ZZ)$ and $σ(VBF)BR(H \rightarrow WW)$ for VBF production processes, $σ(ggH)BR(H \rightarrow WW)$ and $σ(ggH)BR(H \rightarrow ZZ)$ for gluon fusion production process at 13 and 14 TeV and found good agreement with experimental data.
