Measurement of the forward-backward asymmetry in the distribution of leptons in tt events in the lepton+jets channel
Original language description
We present measurements of the forward-backward asymmetry in the angular distribution of leptons from decays of top quarks and antiquarks produced in proton-antiproton collisions. We consider the final state containing a lepton and at least three jets. The entire sample of data collected by the D0 experiment during Run II of the Fermilab Tevatron Collider, corresponding to 9.7 inverse fb of integrated luminosity, is used. The asymmetry measured for reconstructed leptons is AlFB=(2.92.1(stat.)+1.51.7(syst.))%. When corrected for efficiency and resolution effects within the lepton rapidity coverage of |yl|<1.5, the asymmetry is found to be AlFB=(4.22.3(stat.)+1.72.0(syst.))%. Combination with the asymmetry measured in the dilepton final state yields AlFB=(4.22.0(stat.)1.4(syst.))%. We examine the dependence of AlFB on the transverse momentum and rapidity of the lepton.
