Search for the SM Higgs~boson in the diboson decay modes with the ATLAS detector

A Higgs~boson search in the $H\to\gamma\gamma$ $H\to WW\to\ell\nu\ell\nu$ and $H\to ZZ^{(*)}\to4\ell$ decay modes has been performed using proton-proton collisions collected in 2011 and 2012 with the ATLAS detector. Updated results on the observed resonance using up to 4.7~fb$^{-1}$ of $\sqrt{s}=7$~TeV and 13.0~fb$^{-1}$ of $\sqrt{s}=8$~TeV data including first measurement of its properties are presented.
