Status of theoretical predictions for top pair production cross section

Abstract

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.
