This paper presents an investigation into the properties of the new particle discovered in the search for the Standard Model Higgs boson by the ATLAS experiment at the LHC. The searches in the H → ZZ(*) → 4ℓ, H → γγ, H → WW(*) → ℓνℓν , H → H → τ+τ− and H → bb̅ channels include several exclusive final states, which provide sensitivity to the coupling properties of the observed particle through the various production and decay modes. Several benchmarks are considered that are designed to probe different aspects of the SM Higgs boson couplings. No significant deviation from the prediction for a SM Higgs boson is found.
