Measurement of the Properties of the top Quark at DØ

Abstract

Different measurements of the properties of the top quark using up to $5.4f{b}^{-1}$ collected with the DØ detector at the Fermilab Tevatron collider are presented. The top mass is obtained from a study of dilepton and lepton+jets final states, while the width is obtained from a combination of the measurements of the single top production via t-channel exchange and the determination of the t \rightarrow Wb branching ratio. Furthermore the measurement of the helicity of the W boson from top quark decays, a measurement of $t\bar{t}$ spin correlations and a measurement of the jet pull (color flow) in $t\bar{t}$ events are presented.
