We compute the electroweak O(alpha(3)alpha(s)) corrections to three-jet production and related event-shape observables at electron-positron colliders. We properly account for the experimental photon isolation criteria and for the corrections to the total hadronic cross section. Corrections to the three-jet rate and to normalised event-shape distributions turn out to be at the few-percent level. (C) 2009 Elsevier B.V. All rights reserved.
