Measurement of the forward-backward charge asymmetry and extraction of sin^2Theta^{eff}_W in ppbar -> Z/γ^{*}+X -> 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 $p\bar{p}\to Z/{\gamma }^{\ast }+X\to e^{+}{e}^{-}+X$ 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 $si{n}^{2}Thet{a}_W^{eff}=0.2327\pm 0.0018(stat.)\pm 0.0006(syst.)$.
