Implementierung eines Algorithmus für den LHCb Level-1 vertex-trigger

Current high-energy experiments for precision measurement of CP violation on the basis of B mesons from hadronic reactions make great demands on the trigger system. Only a very small fraction of all produced events qualifies for such analysis. In this thesis an algorithm for the Level-1 vertex trigger of the future LHCb detector at CERN is developed and implemented with the GAUDI framework. It recognizes and reconstructs secondary vertices with a significant distance from the primary interaction point. The existence of these is interpreted as an indication of the presence of interesting B decays in the event. The processing time is measured in great detail and the reconstruction results are qualitatively analyzed.
