Measurements of Higgs boson production and couplings in diboson final states with the ATLAS detector at the LHC
| Resumo: | Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H → γγ , H → Z Z∗ → 4 and H → W W ∗ → ν ν. The results are based on the complete pp collision data sample recorded by the ATLAS experiment at the CERN Large Hadron Collider at centre-of-mass energies of √s = 7 TeV and √s = 8 TeV, corresponding 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 to loop-induced production and decay modes, are presented. All measurements are consistent with expectations for the Standard Model Higgs boson. |
