Paarproduktion schwerer Quarks in e+ e- -Kollisionen: QCD-Strahlungskorrekturen für die Quark-Antiquark-Beiträge zur Ordnung alpha s 2
In this thesis the QCD corrections to second order in the strong coupling constant, i.e. to order alpha_s^2, for the process e^+ e^- -> Q Qbar are calculated. These are important contributions to the differential cross section of the reaction e^+ e- -> Q Qbar + X. The decay amplitude of a virtual …

Suche nach dem Higgs-Boson in hadronischen Endzuständen mit fehlender Energie am L3-Experiment bei LEP
… taken by the L3 experiment at the Large Electron Positron Collider (LEP) near Geneva during the years 1998 until 2000, which corresponds to an integrated luminosity of 629.7/pb and which were collected in a center-of-mass energy range from 189 GeV to 209 GeV. The Higgs boson searches presented …

Messung der Reaktion e+ e- ZZ q anti-q l+ l mit dem L3-Detektor bei LEP
In this thesis measurements of the pair production of Z bosons and their decay into a final state with two quarks and two charged leptons are performed. The data have been recorded in the years 1997 to 2000 with the L3 experiment at CERN in Geneva. The integrated luminosity of this data set is 683 …
