摘要：
Precision studies of QCD at e(+)e(-) colliders are based on measurements of event shapes and jet rates. To match the high experimental accuracy, theoretical predictions to next-to-next-to-leading order (NNLO) in QCD are needed for a reliable interpretation of the data. We report the first calculation of NNLO corrections (O(alpha(3)(s))) to three-jet production and related event shapes, and discuss their phenomenological impact.
