Top pair production measurements at ATLAS

Measurements of the inclusive and differential top-quark pair cross sections in proton-proton collisions at both 8 TeV and 13 TeV with the ATLAS detector at the Large Hadron Collider are presented. The inclusive measurements reach high precision and are compared to the best available theoretical calculations. Differential measurements of the kinematic properties of the top quark production are also discussed. These measurements, including results using boosted top quarks, probe our understanding of top pair production in the TeV regime. The results, extrapolated to particle and parton level, are compared to Monte Carlo generators predictions implementing LO and NLO matrix elements matched with parton showers and NNLO QCD calculations.
