Progress in top-pair production at hadron colliders    [PDF]

Peter Baernreuther, Michal Czakon, Alexander Mitov

We review recently derived NNLO QCD results for top-pair production at hadron colliders. We compare the size of the NNLO corrections in $q\bar q\to t\bar t+X$ with the LO and NLO ones, and address the question of convergence of perturbative series. We compare the NLO and NNLO K-factors for the Tevatron.
