Top-Quark Physics at the Tevatron

The Tevatron experiments, CDF and DØ have by now analysed collision data corresponding an integrated luminosity of more than 2 fb−1 and the selected data sets comprise several hundreds of reconstructed pairs. Run II of the Tevatron has thus paved the way for a new era in top quark physics focussing on the precise measurement of top quark properties. This article gives a concise overview on the status of measurements in the top quark sector by CDF and DØ including cross section measurements, the measurement of the charge asymmetry in top-antitop events, the search for top-antitop resonances, the measurement of the W helicity in top quark decays, and the search for flavor-changing neutral current top quark decays. The measurements of intrisic top quark properties, mass, width and charge, are discussed. The article concludes with a presentation of first measurements of single top-quark production.
