Query: Measurement of the forward-backward asymmetry in top-antitop quark
  production in proton-antiproton collisions   We present a new measurement of the forward-backward asymmetry in ttbar
production in ppbar collisions in the lepton+jets channel at D0. We measure
asymmetries from two different observables and unfold the data to allow the
results to be compared to standard model predictions. For the unfolded
asymmetry based on the Delta-y variable, we measure (19.6 +/- 6.5)%, compared
with an MC@NLO-based prediction of (5.0 +/- 0.1)%. We also discuss the
correlation between the asymmetry and the transverse momentum of the ttbar
system.
