论文摘要
我们提出了一环公式，以在标准模型框架中为't Hooft-Veltman仪表中的$ hzz $顶点做出贡献。在最终州的$ z $玻色子中，对一环脱壳型衰减率to $ z $ pair进行了调查。当我们将外壳Higgs Mass从$ 200 $ GEV更改为$ 500 $ GEV时，更正的价格为$ 7 \％\％\％\％\％$。 In applications, we study off-shell Higgs decay $H^* \rightarrow ZZ$ in the Higgs productions at future colliders such as the signal processes $γ^*(Q^2)γ\rightarrow H^* \rightarrow ZZ$ and $e^-γ\rightarrow e^-H^* \rightarrow e^- ZZ$ are analyzed.
We present one-loop formulas for contributing to the $HZZ$ vertex in 't Hooft-Veltman gauge within Standard Model framework. One-loop off-shell Higgs decay rates to $Z$-pair are investigated in both unpolarized and longitudinal polarization for $Z$ bosons in final state. The corrections are range of $7\%$ to $8.4\%$ when we vary the off-shell Higgs mass from $200$ GeV to $500$ GeV. In applications, we study off-shell Higgs decay $H^* \rightarrow ZZ$ in the Higgs productions at future colliders such as the signal processes $γ^*(Q^2)γ\rightarrow H^* \rightarrow ZZ$ and $e^-γ\rightarrow e^-H^* \rightarrow e^- ZZ$ are analyzed.
