Description
A search is presented for the Higgs boson off-shell production in gluon
fusion and vector boson fusion processes with the Higgs boson decaying
into a W+W- pair and the W bosons decaying
leptonically. The data observed in this analysis are used to constrain
the Higgs boson total decay width. The analysis is based on the data
collected by the CMS experiment at the LHC, corresponding to integrated
luminosities of 4.9 fb-1 at a centre-of-mass energy of 7 TeV
and 19.4 fb-1 at 8 TeV, respectively. An observed (expected)
upper limit on the off-shell Higgs boson event yield normalised to the
standard model prediction of 2.4 (6.2) is obtained at the 95% CL for the
gluon fusion process and of 19.3 (34.4) for the vector boson fusion
process. Observed and expected limits on the total width of 26 and 66
MeV are found, respectively, at the 95% confidence level (CL). These
limits are combined with the previous result in the ZZ channel leading
to observed and expected 95% CL upper limits on the width of 13 and 26
MeV, respectively. [Figure not available: see fulltext.]
