Charged Higgs Bosons at the ATLAS Experiment and Beyond

by Coniavitis, Elias, PhD

Abstract (Summary)
In the ATLAS experiment at the Large Hadron Collider (LHC) at CERN, direct searches for the elusive Higgs boson will be conducted, as well as for physics beyond the Standard Model. The charged Higgs boson (H±) is interesting both as a part of the Higgs sector, and as a clear sign of new physics. This thesis focuses on H± searches, with H± production in top-antitop pair events, and in particular the  bW± bH±, H±??had?, W±?qq channel. Its potential was investigated  as  part of a larger study of the expected performance of the entire ATLAS experiment. Full simulation of the ATLAS detector and trigger was used, and all dominant systematics considered. It was shown to be the most promising H± discovery channel for mH±Bibliographical Information:
