Abstract

We calculate the O(α_s) corrections to longitudinal spin-spin correlations in e⁺e⁻ → qq¯. For top quark pair production the O(α_s) corrections to the longitudinal spin-spin asymmetry amount to less than 1% in the q²-range from above tt^¯-threshold up to q² = 1000 GeV . In the e⁺e⁻ → b^¯b case the O(α_s) corrections reduce the asymmetry value from its m = 0 value of −1 to approximately −0.96 for q²-values around the Z-peak.
