Combined measurements of the Higgs boson production and decay rates in H->ZZ*->4l and H->gamgam decay channels using pp collisions at √s = 13 TeV with the ATLAS Experiment

After the Higgs boson was discovered at LHC in 2012, it is of great importance to study Higgs boson's production and decay rates in order to understand how it interacts with Standard Model particles. In this presentation, I will report the combined measurements of Higgs boson production and decays in H->ZZ*->4l and H->gamgam decay channels using LHC Run 2 proton-proton collision data collected at center-of-mass energy of 13 TeV by the ATLAS detector in 2015 and 2016. I will also discuss how the measurements constrain the Higgs boson’s couplings to Standard Model particles as well as the existence of new physics.
