Electroweak and Top physics at ATLAS

The observation of electroweak boson ($W,Z$) and top quark pair ($tar{t}$) production is one of the key milestones for the early LHC physics programme. Production of $tar{t}$, $W$ and $Z$ in association with jets are important backgrounds in various searches for physics beyond the Standard Model, and new physics may also give rise to additional production mechanisms or modification of the decay channels. This note summarizes the electroweak and top physics performed in ATLAS with $sqrt{s}=7~TeV$ proton-proton collisions during 2010 and compares the observations with theoretical predictions.
