Top quark pair production at complete NLO accuracy with NNLO+NNLL′ corrections in QCD.

Czakon, Michał and Ferroglia, Andrea and Mitov, Alexander and Pagani, Davide and Papanastasiou, Andrew S. and Pecjak, Benjamin D. and Scott, Darren J. and Tsinikos, Ioannis and Wang, Xing and Yang, Li Lin and Zaro, Marco (2020) 'Top quark pair production at complete NLO accuracy with NNLO+NNLL′ corrections in QCD.', Chinese physics C., 44 (8). 083104.


We describe predictions for top quark pair differential distributions at hadron colliders, by combining the next-to-next-to-leading order quantum chromodynamics calculations and next-to-leading order electroweak corrections with double resummation at the next-to-next-to-leading logarithmic accuracy of threshold logarithms and small-mass logarithms. To the best of our knowledge, this is the first study to present such a combination, which incorporates all known perturbative information. Numerical results are presented for the invariant-mass distribution, transverse-momentum distribution, and rapidity distributions.
