Measurement of the forward-backward charge asymmetry in top-quark pair production

Abstract:

We present the first measurement of the integrated forward-backward charge asymmetry in top-quark "top-antiquark pair (tt) production in proton-antiproton (pp) collisions in the lepton+jets final state. Using a b-jet tagging algorithm and kinematic reconstruction assuming tt+X production and decay, a sample of 0.9 fb-1 of data, collected by the D0 experiment at the Fermilab Tevatron Collider, is used to measure the asymmetry for different jet multiplicities. The result is also used to set upp...
