Measurement of the forward-backward charge asymmetry and extraction of sin2thetaWeff in pp--&gt;Z/gamma* + X--&gt;e+e- +X events produced at sqrt[s] = 1.96 TeV.

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).
