We present the first model-independent measurement of the helicity of W bosons produced in top quark decays, based on a 1 fb;{-1} sample of candidate tt[over ] events in the dilepton and lepton plus jets channels collected by the D0 detector at the Fermilab Tevatron pp[over ] Collider. We reconstruct the angle theta;{*} between the momenta of the down-type fermion and the top quark in the W boson rest frame for each top quark decay. A fit of the resulting costheta;{*} distribution finds that the fraction of longitudinal W bosons f_{0}=0.425+/-0.166(stat)+/-0.102(syst) and the fraction of right-handed W bosons f_{+}=0.119+/-0.090(stat)+/-0.053(syst), which is consistent at the 30% C.L. with the standard model.
