Power correction analyses in e+e- annihilation
Abstract
The current status of theoretical work and experimental analyses on power corrections in QCD for e+e- annihilation will be reviewed. Measurements of the number of active quark flavours nf and the QCD colour factors CA and CF derived from QCD fits to event shape distributions at lower energies and LEP energies will be presented. The fits are based on O(alphas2)+NLLA QCD predictions with power corrections to model hadronisation.
