Conference paper

Abstract

The astonishingly successful Standard Model has too many free parameters and ad-hoc features to be considered as really satis factory. As a consequence, many experiments were undertaken to search for deviations from the predictions of this model in the entire energy-range accessible. These deviations would clearly provide im portant indications for more global unification-schemes of particles and interactions[1],[2],[3].
