Abstract

In 1995, the top quark was discovered at the Fermilab Tevatron Collider by the CDF and DØ collaborations in the collisions at √s = 1.8 TeV using about 50 pb^-1 of data per experiment. We present the studies of the top quark properties based on 1 fb^-1 of data collected by the DØ experiment at a center of mass energy of 1.96 TeV. The increased statistics and higher collision energy allow to perform precision measurements of the top quark production and decay characteristics and open the possibility to probe physics beyond the Standard Model in the top quark sector. The presentation mainly focuses on the measurement of the top pair production cross section and branching fraction of the top quark decays, a search for resonances, and the measurement of the top quark pair production cross section ratio and its interpretation in terms of new physics.
