Sumario:Measurements of production, couplings and spin properties of the recently discovered Higgs boson using the most sensitive channels, $H \rightarrow \gamma \gamma$, $H \rightarrow ZZ \rightarrow 4 l$ and $H \rightarrow WW \rightarrow l \nu l \nu$, are presented. The results are based on the complete pp collision data sample recorded by the ATLAS and CMS experiments at the CERN Large Hadron Collider at centre-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of about 25 fb$^{-1}$. Other important final states are also briefly described, as $H \rightarrow \tau \tau$, $H \rightarrow bb$, $H \rightarrow Z \gamma$ and $H\rightarrow \mu \mu$. All studies are consistent with expectation for the Standard Model Higgs boson. Finally, two analyses with a high resonance search up to 1 TeV are summarised, namely $H\rightarrow ZZ \rightarrow 2 l 2 \nu$ and $H \rightarrow W W \rightarrow l \nu J$. No evidence for an additional signal is found in the region 248-930 GeV at 95\% CL.
