  A search for a heavy Higgs boson in the H to WW and H to ZZ decay channels is
reported. The search is based upon proton-proton collision data samples
corresponding to an integrated luminosity of up to 5.1 inverse femtobarns at
sqrt(s) = 7 TeV and up to 19.7 inverse femtobarns at sqrt(s) = 8 TeV, recorded
by the CMS experiment at the CERN LHC. Several final states of the H to WW and
H to ZZ decays are analyzed. The combined upper limit at the 95% confidence
level on the product of the cross section and branching fraction exclude a
Higgs boson with standard model-like couplings and decays in the range 145 <
m[H] < 1000 GeV. We also interpret the results in the context of an electroweak
singlet extension of the standard model.
