Contribution
First comprehensive set of top-quark measurements and new physics searches with early LHC data from the ATLAS detector.
Findings
Measured top-quark pair and single top production rates.
Determined top-quark mass and spin correlations.
Conducted searches for physics beyond the Standard Model.
Abstract
With data collected during the first half of 2011 pp run of the Large Hadron Collider at \surds = 7 TeV, a substantial data sample of high p_T triggers, 1.08/fb, has been collected by the ATLAS detector. Measurements of the production of top-quark pairs and single top-quarks in different channels, the top-quark mass, the top-quark pair charge asymmetry and spin correlations, and the W helicity fractions in top-quark decays are presented, as well as two searches for new physics effects involving top-quark pairs.
