QCD and Top physics results with 2010 ATLAS Data

In 2010, ATLAS collected proton-proton collision data at a centre-of-mass energy of 7 TeV, for an integrated luminosity of ~35 pb-1. The high energy gave the possibility to produce a sizeable amount of top quarks, allowing for measurements of top quark properties and searches for BSM-predicted heavy resonances decaying in top-antitop pairs. Moreover, the large phase space at this energy enabled the study of W and Z gauge boson production in association with multijet topologies, which constitute a significant experimental background for Higgs and BSM searches at LHC. This talk will give an overview of the top physics and multijet QCD results of 2010, with an outlook on perspectives for 2011.
