Top properties measurements with the ATLAS detector

The top quark is unique among the known quarks in that it decays before it has an opportunity to form hadronic bound states. This makes measurements of its properties particularly interesting as one can access directly the properties of a bare quark. A measurement of the charge asymmetry in top quark pair events are presented. The measurements uses the 7 TeV ATLAS dataset and probes models of physics beyond the Standard Model. A measurement of the correlation between the direction of the spins of top quark pairs is also presented. The measurement agrees with the Standard Model and is used to set limits on the production of the supersymmetric partner of the top quark. In addition, a novel measurement of colour flow in top quark pair events is presented. The measurement uses the jets originating from the W boson and demonstrates the ability of the colour flow observable to distinguish between colour octet and colour singlet final states.
