Measurements are presented of the production properties, couplings and spin-parity of the recently discovered Higgs-like boson using the decays into boson pairs, γγ, ZZ∗→ 4ℓ and WW∗→ ℓνℓν. The results shown here are based on the complete pp collision data sample recorded by the ATLAS experiment at the Large Hadron Collider (LHC) at centre-of-mass energies of √s = 7 TeV and √s = 8 TeV, and correspond to an integrated luminosity of about 25 fb−1. Evidence for Higgs boson production through vector-boson fusion is reported. Results of combined fits probing Higgs boson couplings to fermions and bosons, as well as anomalous contributions of loop-induced production and decay modes, are presented. The spin–parity hypothesis JP = 0+, predicted for the Standard Model Higgs boson, is compared to alternative hypotheses (JP = 0−1, 1+,1− and 2+). All measurements are consistent with the Standard Model expectations of the Higgs boson.
