Study of the Higgs boson properties by combining different production and decay channels

The poster is about combined measurements of Higgs boson production cross sections and branching fractions using the $H\rightarrow\gamma\gamma$ and $H\rightarrow ZZ^*\rightarrow4l$ decay channels, based on 36.1 $\text{fb}^{-1}$ of proton–proton collision data recorded by the ATLAS experiment at the LHC at $\sqrt{s}=13$ TeV.
