Precision measurements of the Top quark with the ATLAS experiment

Abstract

The top quark is the heaviest known fundamental particle. As it is the only quark that decays before it hadronizes, this allows the unique opportunity to probe the properties of bare quarks. In this paper the most recent precision measurements of the top quark properties, performed by the ATLAS experiment using data from proton-proton collisions at p s = 8 TeV and p s = 7 TeV are reviewed. The top pair and single top production cross-sections, including differential distributions, alongside some top quark properties measurements are shown. Interpretations in terms of limits on physics beyond the standard model and searches for new physics using top quarks will also be presented
