Analytic three-loop QCD corrections to top-quark and semileptonic $b \to u$ decays

Long-Bin Chen, Hai Tao Li, Zhao Li +3

We present the first analytic results of N $^{3}$ LO QCD corrections to the top-quark decay width. We focus on the dominant leading color contribution, which includes light-quark loops…

Categorization of two-loop Feynman diagrams in the $O (α^{2})$ correction to $e^{+} e^{-} \to Z H$

Zhao Li, Yefan Wang, Quan-feng Wu

The $e^{+} e^{-} \to Z H$ 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…
