Top quark production with the ATLAS detector at LHC

The top quark is the most massive known fundamental constituent of matter. Its unexplained large mass suggests an important connection to the still mysterious electroweak symmetry breaking mechanism and it is the basis of a rich set of links to possible new particle and interactions that could appear at the LHC by often modifying the production and decay of top quarks. Unprecedentedly abundant top quark production in proton proton collisions at the Large Hadron Collider (LHC) is now opening doors on increasingly precise measurements of top quark pair and single production, also at the differential level. The most recent results on these topics will be reviewed using the data collected by the ATLAS detector at the LHC.
