摘要

This dissertation presents the measurements of Higgs boson coupling properties using the entire Run 1 proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider. The study combines individual analysis results from H → gammagamma, ZZ*, WW*, tautau, bb, mumu and Zgamma decay modes, and from the constraints on ttH and off-shell Higgs boson production, which provides an extensive coverage of both fermions and gauge bosons. The measured signal yield of all Higgs production and decay processes, normalized to the SM expectation, is found to be [special characters omitted]. The coupling strength measurements are based on a leading-order (LO) tree-level-motivated framework, with different assumptions on the loop-induced processes and the Higgs total decay width. All benchmark models considered are found to be compatible with the SM predictions and no significant deviations from the SM expectations of Higgs boson coupling strengths are observed.
