A measurement of sine(2)theta(W) from the forward-backward asymmetry in proton-antiproton going to Z boson positron-electron interactions at sqrt.s = 1.8 TeV

An analysis of the forward-backward asymmetry in Z$\sp{0}$ decays using data from the Collider Detector at Fermilab provides a measurement of sin\sp2\barθ\sb{\rm W}. The forward-backward asymmetry is measured to be (5.2 $\pm$ 5.9 (stat) $\pm$ 0.4 (sys))%, which implies sin\sp2\barθ\sb{\rm W} = 0.288$\sbsp{-0.015}{+0.017}$ (stat) $\pm$ 0.002 (sys), after QCD, QED, and weak corrections. When higher order weak corrections are included, the measured value of sin\sp2θ\sb{\rm W} is consistent with previous measurements over a broad range of top quark masses.
