Description
Measurements of the inclusive top quark pair production cross sections
in proton-proton collisions with the ATLAS detector at the Large Hadron
Collider are presented. The most precise result requires opposite sign
electrons and muons and uses the full data-set at a centre-of-mass energy
of 7 and 8 TeV. In addition, differential measurements of the top transverse
momentum and kinematic properties of the top-anti-top pair are discussed.
These measurements, including results using boosted tops, probe our
understanding of top pair production in the TeV regime. The results,
unfolded to particle and parton level, are compared to recent Monte Carlo
generators implementing LO and NLO matrix elements matched with parton
showers and NLO QCD calculations. In addition, measurements of the production
of top quark pairs in association with gauge bosons or jets are presented.
