Measurements of Higgs boson properties with the ATLAS detector

This talk presents precise measurement of the properties of the Higgs boson, including its mass, total width, spin, couplings and CP quantum number. The measurements are performed in various Higgs boson production and decay modes, as well as their combinations. Observation of deviations between these measurements and Standard Model (SM) predictions would be a sign of possible new phenomena beyond the SM. The talk covers: 1) Measurement of the Higgs boson mass in the H→ZZ∗→4l decay channel; 2) Constraints on the total width of the Higgs boson in the the ZZ→4l and ZZ→2l2ν decay channels; 3) CP properties of the Higgs boson coupling to electroweak bosons in the VBF H→𝛾𝛾 channel; 4) CP properties of Higgs boson interactions with τ leptons; 5) CP nature of the top-Higgs Yukawa coupling in ttH and tH events with H→bb and with H→𝛾𝛾
