Abstract
<jats:p> Two measurements of the W-helicity in [Formula: see text] decays at [Formula: see text] have been carried out using data collected by the DØ detector. Semileptonic [Formula: see text] events in the electron and muon channel were used. In these events the distribution of the angle between the lepton and the direction of the top measured in the rest frame of the intermediate W boson is sensitive to the helicity of the W. The two analyses differ in the usage of lifetime tag information in the event selection. With an integrated luminosity of 169 pb<jats:sup>-1</jats:sup> and 158 pb<jats:sup>-1</jats:sup> in the e+jets and μ+jets channels respectively, an upper limit on the fraction f<jats:sub>+</jats:sub> of positive helicity W's of f<jats:sub>+</jats:sub>&lt;0.244 is set by both analyses at 90% confidence level. </jats:p>
