摘要

本文综述了差分水平上顶对产生和衰减的理论预测现状。对于稳定顶，我们重点研究了NNLO QCD+ NNLO EW组合，NNLO+NNLL$'$计算和合并的$t \bar t+t \bar t j$结果在NLO QCD+EW精度。我们进一步介绍了在QCD中NLO的顶夸克对的半轻子衰变模式中的脱壳效应。

Status of theoretical predictions for top pair production cross section

In this proceeding we review the status of theoretical predictions for top pair production and decay at differential level. Concerning stable tops we focus on the NNLO QCD+NLO EW combination, the NNLO+NNLL$'$ calculation and the merged $t \bar t+t \bar t j$ results at NLO QCD+EW accuracy. We further present results at the decay level including off-shell effects in the semi-leptonic decay mode of the top-quark pair at NLO in QCD.
