We present a measurement of the forward-backward charge asymmetry (AFB) in pp-bar→Z/γ∗+X→e(+)e(−)+X events at a center-of-mass energy of 1.96 TeV using 1.1 fb(−1) of data collected with the D0 detector at the Fermilab Tevatron collider. AFB is measured as a function of the invariant mass of the electron-positron pair, and found to be consistent with the standard model prediction. We use the AFB measurement to extract the effective weak mixing angle sin(2)θ[eff over W]=0.2326±0.0018(stat)±0.0006(syst).
