Description
Combined ATLAS and CMS measurements of the Higgs boson production and
decay rates, as well as constraints on its couplings to vector bosons
and fermions, are presented. The combination is based on the analysis of
five production processes, namely gluon fusion, vector boson fusion, and
associated production with a W or a Z boson or a pair of top quarks, and
of the six decay modes H → ZZ, W W , γγ , ττ,
bb, and μμ. All results are reported assuming a value of 125 .09
GeV for the Higgs boson mass, the result of the combined measurement by
the ATLAS and CMS experiments. The analysis uses the CERN LHC
proton-proton collision data recorded by the ATLAS and CMS experiments
in 2011 and 2012, corresponding to integrated luminosities per
experiment of approximately 5 fb-1 at √{s}=7 TeV and 20
fb-1 at √{s}=8 TeV. The Higgs boson production and decay
rates measured by the two experiments are combined within the context of
three generic parameterisations: two based on cross sections and
branching fractions, and one on ratios of coupling modifiers. Several
interpretations of the measurements with more model-dependent
parameterisations are also given. The combined signal yield relative to
the Standard Model prediction is measured to be 1 .09 ± 0 .11.
The combined measurements lead to observed significances for the vector
boson fusion production process and for the H → ττ decay of
5 .4 and 5 .5 standard deviations, respectively. The data are consistent
with the Standard Model predictions for all parameterisations
considered. [Figure not available: see fulltext.][Figure not available:
