Helicity of the W boson in lepton + jets t anti-t events,
Original language description
We examine properties of t anti-t candidazes in lepton+jet final states to establish the helicities of the W bosons in t?W+b decays. Our analysis is based on a direct calculation of a probability that each event corresponds to a t anti-t final state, asa function of the W boson. We use the 125 events/pb sample of data collected by the D0 experiment during Run 1 of the Fermilab Tevatron collider at ?s=1.8 TeV, and obtain a longitudinal helicity fraction of Fo=0.56+/-0.31, which is consistent with the prediction of Fo=0.70 from the standard model
