Description

We present the measurement of forward-backward charge asymmetry AFB in pp̄ → Z/γ∗ → μ+μ− events using 9.7 fb−1 of pp̄ data collected at sqrt s = 1.96 TeV by the D0 detector at the Fermilab Tevatron collider. AFB is measured as a function of the invariant mass of the dilepton system to extract the effective weak mixing angle sin2θeff. We discuss the combination of the four measurements of AFB in pp̄ → Z/γ∗ → e+e− /μ+μ− + X events using the full datasets collected by the D0 and CDF detectors at the Tevatron and present the indirect extraction of the W mass in the context of the standard model.
