Colour Reconnection - Models and Tests

Abstract

Recent progress on colour reconnection within the Pythia framework is presented. A new model is introduced, based on the SU(3) structure of QCD and a minimization of the potential string energy. The inclusion of the epsilon structure of SU(3) gives a new baryon production mechanism and makes it possible simultaneously to describe hyperon production at both $e^{+}{e}^{-}$ and pp colliders. Finally, predictions for $e^{+}{e}^{-}$ colliders, both past and potential future ones, are presented.
