Abstract

An update of a previous search for the standard model Higgs boson decaying to W+W in pp collisions at √s = 7 TeV and √s = 8 TeV is reported. The event sample corresponds to the full integrated luminosity collected by the CMS detector at the LHC in 2011 and 2012, corresponding to 4.9 fb-1 and 19.5 fb-1, respectively. The W+W candidates are selected in events with two oppositely charged leptons and large missing transverse momentum. An excess of events is observed above background which is consistent with the expectations from a standard model Higgs boson of mass around 125 GeV and has a statistical significance of 4.0 standard deviations for this mass. This result provides evidence for a Higgs-like particle decaying to W+W. Additional standard model Higgs-like bosons are excluded in the mass range 128-600 GeV at 95% confidence level. The hypothesis of the standard model Higgs boson for quantum numbers and couplings is tested against the spin-2 hypothesis of a narrow resonance produced through the gluon fusion mechanism and with minimal couplings to the W+W pair.
