We present the first measurement of the color representation of the hadronically decaying W boson in ttbar events, from 5.3fb-1 of integrated luminosity collected with the D0 experiment. A novel calorimeter-based vectorial variable, “jet pull,” is used, sensitive to the color-flow structure of the final state. We find that the fraction of uncolored W bosons is 0.56±0.42(stat+syst), in agreement with the standard model.
