Impacts of misalignment in the ATLAS Muon Spectrometer on the measured Z-Boson resonance

The study of the Z Boson and its decay into two muons at ATLAS provides several interesting aspects. Since the mass and the width of the Z-Boson is known to a very high precision from LEP experiments, Z decays can be used for precision tests of the detector, in particular for alignment issues. Various effects of misalignments in the ATLAS Muon Spectrometer on the reconstructed Z-Boson resonance are discussed. Moreover, the impacts on the precision of muon momentum reconstruction were studied.
