Bestimmung der Kopplungsstruktur des Higgs-Bosons mit dem Atlas-Detektor

Various methods for the determination of the spin-parity of the standard-model Higgs boson are presented and analysed. The coupling of the Higgs to vectorbosons is used to compare angular and mass distributions of the decay products of the standard model with predictions for alternative couplings. The feasibility of the measurement of the parameters used are studied for the Atlas detector. For the first time methods for the exclusion of all alternative Spin 0 and Spin 1 couplings are presented for the whole mass range of interest (120 - 300 GeV). The Atlas experiment will be able to establish the Standard Model Coupling for the the whole mass range discussed, where the required Luminosity varies for different masses between 30 fb^-1 to 300 fb^-1.
