NNLO QCD corrections to event shape variables in electron positron annihilation


Gehrmann-De Ridder, A; Gehrmann, T; Glover, E W N; Heinrich, G (2008). NNLO QCD corrections to event shape variables in electron positron annihilation. Journal of Physics: Conference Series, 110(2):022014.

Abstract

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(α3s)) to three-jet production and related event shapes, and discuss their phenomenological impact.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
