Categorization of two-loop Feynman diagrams in the $\mathcal{O}({\alpha }^2)$ correction to $e^{+}{e}^{-}\to ZH$

Zhao Li, Yefan Wang, Quan-feng Wu

The $e^{+}{e}^{-}\to ZH$ 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…
