abstract = {We report the observation of Higgs boson decays to WW*
based on an excess over background of 6.1 standard
deviations in the dilepton final state, where the Standard
Model expectation is 5.8 standard deviations. Evidence for
the vector-boson fusion (VBF) production process is obtained
with a significance of 3.2 standard deviations. The results
are obtained from a data sample corresponding to an
integrated luminosity of 25 fb−1 from s=7 and 8 TeV pp
collisions recorded by the ATLAS detector at the LHC. For a
Higgs boson mass of 125.36 GeV, the ratio of the measured
value to the expected value of the total production cross
section times branching fraction is
1.09-0.15+0.16(stat)-0.14+0.17(syst). The corresponding
ratios for the gluon fusion and vector-boson fusion
production mechanisms are 1.02±0.19(stat)-0.18+0.22(syst)
and 1.27-0.40+0.44(stat)-0.21+0.30(syst), respectively. At
s=8 TeV, the total production cross sections are measured to
be σ(gg→H→WW*)=4.6±0.9(stat)-0.7+0.8(syst) pb and
σ(VBF H→WW*)=0.51-0.15+0.17(stat)-0.08+0.13(syst) pb. The
fiducial cross section is determined for the gluon-fusion
process in exclusive final states with zero or one
associated jet.},
