Resumen
We calculate the O(αs) corrections to longitudinal spin-spin correlations in e+e− → qq¯. For top quark pair production the O(αs) 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(αs) corrections reduce the asymmetry value from its m = 0 value of −1 to approximately −0.96 for q2-values around the Z-peak.
