- Аннотация: Combined measurements of Higgs boson production cross sections and branching fractionsare presented. The combination is based on the analyses of the Higgs boson decay modesH → γγ, ZZ∗, WW∗, ττ, bb¯, µµ, searches for decays into invisible final states, and onmeasurements of off-shell Higgs boson production. Up to 79.8 fb−1 of proton–proton collisiondata collected at √s = 13 TeV with the ATLAS detector are used. Results are presented forthe gluon–gluon fusion and vector-boson fusion processes, and for associated production withvector bosons or top-quarks. The global signal strength is determined to be µ = 1.11+0.09−0.08.The combined measurement yields an observed (expected) significance for the vector-bosonfusion production process of 6.5σ (5.3σ). Measurements in kinematic regions defined withinthe simplified template cross section framework are also shown. The results are interpretedin terms of modifiers applied to the Standard Model couplings of the Higgs boson to otherparticles, and are used to set exclusion limits on parameters in two-Higgs-doublet models andin the simplified Minimal Supersymmetric Standard Model. No significant deviations fromStandard Model predictions are observed.
