Measurement of the top pair production cross section and properties of top quark production and decay in proton-antiproton collisions at 1.96 TeV center-of-mass energy using the D0 Detector

Abstract

An overview over measurements of top quark pair production in pp collisions at a center-of-mass energy of √ s = 1.96 TeV is given. Emphasis is given to measurements of the tt cross section in lepton+jets and dilepton final states with up to 5.4 fb −1 of integrated luminosity. Examples of measurements of top quark properties such as a measurement of the top quark branching ratio, a search for flavor changing neutral current couplings in top quark decays and an extraction of the top quark pole and MS mass using the tt cross section are presented.
