Measurements of the Higgs boson production and decay rates and constraints on its couplings at the LHC

ATLAS and CMS Higgs boson analyses have been combined to precisely measure the Higgs boson mass. The result is $m_H=125.09\pm 0.24$ GeV. Combined measurements of the Higgs boson production and decay rates, and constraints on its couplings to other particles have been obtained. The results are based on the proton-proton collision data collected at the LHC with the ATLAS and CMS detectors in 2011 and 2012, corresponding to integrated luminosities per experiment of approximately~5~$\mathrm{fb}^{-1}$ at $\sqrt{s}=7$ TeV and 20~$\mathrm{fb}^{-1}$ at $\sqrt{s} = 8$~TeV. The combined signal yield relative to the standard model prediction is $1.09\pm 0.11$. Many other measurements have been carried out in more or less constrained assumptions and all measurement are consistent with the standard model. The increased sensitivity coming from the combination of the two experiments allows to obtain a significance of $5.4\sigma$ for the $V$BF~production process and of~$5.5\sigma$ for Higgs boson decays into $\tau$-lepton pairs.
