Higgs boson couplings to bosons with the ATLAS detector: run 1 legacy

The final ATLAS measurements of Higgs boson production and couplings in the decay channels $H \rightarrow ZZ^{(*)} \rightarrow \ell\ell\ell\ell$, $H \rightarrow \gamma\gamma$ and $H \rightarrow WW^{(*)} \rightarrow \ell\nu\ell\nu$ are presented, based on the run 1 of the LHC. The analyses are optimi...

Sumario:The final ATLAS measurements of Higgs boson production and couplings in the decay channels $H \rightarrow ZZ^{(*)} \rightarrow \ell\ell\ell\ell$, $H \rightarrow \gamma\gamma$ and $H \rightarrow WW^{(*)} \rightarrow \ell\nu\ell\nu$ are presented, based on the run 1 of the LHC. The analyses are optimised to measure the number of observed Higgs boson decays divided by the corresponding Standard Model predictions for individual Higgs boson production processes. Total, fiducial and differential cross-sections are also measured. No significant deviations from the predictions of the Standard Model are found.
