- Abstract:
- We present a measurement of the forward-backward charge asymmetry (A FB) in pp-->Z/gamma* + 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. A FB 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 A FB measurement to extract the effective weak mixing angle sin2thetaWeff = 0.2326+/-0.0018(stat)+/-0.0006(syst).
