论文摘要
$ e^+e^ - \ rightarrow zh $流程是Higgs Boson生产的主要过程。为了将HIGGS属性的分析与高度精确的实验数据匹配，将理论预测包括在生产率$σ（e^+e^ - \ rightarrow ZH）中，将理论预测与完整的近代到接头订单级电子效应相匹配至关重要。在这项鼓舞人心的工作中，我们根据相关的拓扑结构将$ \ Mathcal O（α^2）$校正的$ \ Mathcal O（α^2）$校正的两环feynman图分为$ e^+e^ - \ rightarrow zh $。尽管25377个图总共有助于$ \ MATHCAL O（α^2）$校正，但具有七个分母的最具挑战性图的数量为2250，仅包含312个非平面图，具有155种独立类型。这种分类可能是将来完整计算的有价值的参考。
The $e^+e^- \rightarrow ZH$ process is the dominant process for the Higgs boson production at the future Higgs factory. In order to match the analysis on the Higgs properties with the highly precise experiment data, it will be crucial to include the theoretical prediction to the full next-to-next-to-leading order electroweak effect in the production rate $σ(e^+e^-\rightarrow ZH)$. In this inspiring work, we categorize the two-loop Feynman diagrams of the $\mathcal O(α^2)$ correction to $e^+e^- \rightarrow ZH$ into 6 categories according to the relevant topological structures. Although 25377 diagrams contribute to the $\mathcal O(α^2)$ correction in total, the number of the most challenging diagrams with seven denominators is 2250, which contain only 312 non-planar diagrams with 155 independent types. This categorization could be a valuable reference for the complete calculation in the future.
