2. Measurements of Angular Correlations in Minimum Bias Events and Preparatory Studies for Charged Higgs Boson Searches at the Tevatron and the LHC
Abstract : Studies of minimum bias events at colliders probe the behavior of QCD in the non-perturbative regime. The phenomenology of events in this regime is described by empirical models that take many parameters, which all need to be tuned to the observed data. READ MORE

3. Data processing for hybrid systems of detectors : aspects of preparation and analysis of elementary particle experiments at high energy
Abstract : The preparations of experiments for the Fermilab Hybrid System and the European Hybrid Spectrometer are described. The main emphasis is on the contribution to the software for these systems, and particularly the SURVEY programs package, performing the alignment and calibration of the spectrometer. READ MORE

4. First determination of the electric charge of the top quark
Abstract : In this thesis, the first determination of the electric charge of the top quark is presented using 370pb-1 of data recorded by the DØ detector at the Fermilab Tevatron accelerator. ttbar events are selected with one isolated electron or muon and at least four jets out of which two are b-tagged by reconstruction of a secondary decay vertex (SVT).
