Measurements of Higgs boson properties using a combination of different Higgs decay channels

Six years after the first observation of the Higgs boson, the exploration of the Higgs sector of the Standard Model lagrangian remains at full swing. Analysing up to $80\,\mathrm{fb}^{-1}$ of $13\,$TeV collision data recorded during the Run-2 of the LHC, the ATLAS collaboration has produced a number of measurements on the Higgs boson in all its main production modes and in many decay channels. These analyses are combined to measure differential distributions or extract information on the couplings of the Higgs boson.This in turns allows to test the Standard Model predictions in the Higgs boson sector in terms of distributions and couplings, and to set constraints on different scenarios of physics beyond the Standard Model.
