Measurements of Hadronic Asymmetries in $e^{+}e^{-}$ Collisions

High precision experimental new electroweak results measured at the four LEP experiments and the SLD collaboration are discussed. Heavy quark (b b-bar and c c-bar) forward-backward asymmetries measured at LEP are presented along with polarized forward-backward and left-right asymmetries measured at SLD. The results are compared, and the combined averages are used to evaluate the Standard Model parameters.High precision experimental new electroweak results measured at the four LEP experiments and the SLD collaboration are discussed.
