论文摘要
我们介绍了QCD辐射校正对NNLO的重夸克产生的计算。该计算是在\ textsc {matrix}的更新版本中实现的，该版本使我们能够获得稳定的顶级夸克的多差预测。我们还报告了$ b {\ bar b} $生产的NNLO计算，并评论了顶级衰减的包含以及将结果扩展到$ t \ bar th $。
We present the calculation of QCD radiative corrections to heavy-quark production at NNLO. The calculation is implemented in an updated version of \textsc{Matrix}, which allows us to obtain multidifferential predictions for stable top quarks. We also report on the NNLO calculation for $b{\bar b}$ production and comment on the inclusion of top-quark decays and of the extension of our results to $t\bar tH$.
