Measurements of the Higgs boson production and decay rates and coupling strengths using pp collision data at √S=7 and 8 TeV in the ATLAS experiment

Combined analyses of the Higgs boson production and decay rates as well as its coupling strengths to vector bosons and fermions are presented. The combinations include the results of the analyses of the H → γγ, ZZ ∗ , WW ∗ , Zγ, bb, ττ and μμ decay modes, and the constraints on the associated produc...

The results are based on the LHC proton-proton collision datasets, with integrated luminosities of up to 4.7 fb -1 at √S =7 TeV and 20.3 fb -1 at √S = 8 TeV, recorded by the ATLAS detector in 2011 and 2012.
