description | Measurements of the inclusive top quark production cross sections in proton-proton collisions with the ATLAS detector at the Large Hadron Collider are presented. The most precise pair production cross section result requires opposite sign electrons and muons and uses the full data-set at a centre-of-mass energy of 7 and 8 TeV. The first measurements of the ttbar production cross-section at 13 TeV are also presented, using both the dilepton and lepton-plus-jets signatures. Differential measurements of the top transverse momentum and kinematic properties of the top-anti-top pair at 8 TeV 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, the production of top quark pairs in association with vector bosons and additional jets are discussed. These processes are important backgrounds to many new physics searches and the results are compared to the Standard Model predictions. |
