Searching for exotic Higgs boson decays using a low mass double b-tagger
… double b-tagger for use in the context of exotic Higgs decays. After the discovery of the Higgs boson at the Large Hadron Collider, an effort to measure its properties in detail has ensued. Current measurements only constrain non- Standard Model or “exotic” Higgs decays to about < 26%. Allowing …

Search for exotic Higgs boson decays to four leptons with the ATLAS detector
Searches for exotic Higgs boson decays are well motivated by various theoretical models, as well as the constraints from Higgs boson measurement results. The focus is on exotic Higgs boson decays to a pair of beyond-the-Standard-Model spin-0 particles $a$. This dissertation conducts two analyses …

Measurement of Higgs couplings to top quarks and τ leptons with the ATLAS detector
Since the discovery of the Higgs boson in 2012 during the first run of the Large Hadron Collider (LHC) at CERN, extensive measurements have been performed to characterize its properties. Its mass, spin, parity and couplings have been studied in detail with no significant deviations from the SM …

Higher order and CP-violating effects in the neutralino and Higgs boson sectors of the MSSM
… results are presented for neutralino and Higgs decay processes of the form chi^0_i->chi^0_j h_a and h_a->chi^0_i chi^0_j in the MSSM with CP-violating parameters. An on-shell renormalisation scheme is developed for the chargino–neutralino sector that consistently takes into account …

Beyond Standard Model Physics under the ground and in the sky
… physics and cosmology. The implications of the Higgs discovery and lack of new physics results are far reaching. To better understand the nature of Higgs and its connections to electroweak symmetry breaking, we have performed a model independent study of spin-1 contributions in gauge extensions …
