Measurements of the properties of the Higgs boson with the ATLAS detector are presented. The spin, parity and tensor couplings of the Higgs boson in the H → γγ, H → ZZ* → 4l and H → WW* → evμv channels are investigated. The results are based on pp collision data collected by the ATLAS detector corresponding to an integrated luminosity of 4.7 fb−1 at centre-of-mass energy √s = 7 TeV, and 20.3 fb−1 at √s = 8 TeV. Measurements of the fiducial and differential cross sections for Higgs boson production in the H → γγ and H → ZZ* → 4l are also presented using 20.3 fb−1 of √s = 8 TeV data. The cross section measurements in the H → γγ channel are then used to set limits on anomalous Higgs boson interactions in an effective Lagrangian. All results are consistent with expectations for a Standard Model Higgs boson.
