Eleven Years of QCD at LEP
Siegfried Bethke
Abstract
Studies of hadronic final states of e+e- annihilations, observed at the Large Electron Positron Collider LEP at CERN, are reviewed. The topics included cover measurements of αs, hadronic event shapes and hadronisation studies, tests of asymptotic freedom and of the non-Abelian gauge structure of QCD, differences between quark and gluon jets, tests of power corrections and selected results of two-photon scattering processes. The improvements obtained at LEP are demonstrated by comparing to results from the pre-LEP era. This article consists of a reproduction of slides presented at the LEPFest in October 2000, supplemented by a short descriptive text and a list of relevant references.
