Measurement of top properties in ATLAS

The top quark may play a special role in the Standard Model of particle physics. It is, for instance, the heaviest fundamental particle known, with a mass close to the electroweak symmetry breaking scale. Millions of top quark pairs will be produced per year at the LHC at nominal luminosity. ATLAS will measure many of the top quark properties with unprecedented precision. The ATLAS sensitivity studies done with Monte Carlo for the measurements of the top quark mass, the top charge, the rare top quark decays and FCNC, the top spin correlations and W polarization, the anomalous couplings at the Wtb vertex and $t\bar t$ resonances are reviewed.
