Search for SM Higgs decaying to two W bosons at CMS

摘要

Updated results of searches for the standard model Higgs boson decaying to two W bosons in pp collisions at √s=8 TeV are reported. The fully leptonic (WW→ 2?2v) and semileptonic (WW→ ?vjj) final state searches are presented. The event sample corresponds to an integrated luminosity of 12 fb~(-1) collected by the CMS detector in 2012. The 2011 results obtained at √s=7 TeV for an integrated luminosity of 5 fb~(-1) are added to the analysis. The leptonic channel observes an excess at M=125 GeV with a significance of 3.1σ. Upper limits are derived for the remainder of the mass range up to 600 GeV. Results are also presented for Higgs production in association with a W boson, leading to the 3?3v final state using 5 fb~(-1) collected at √s=8 TeV combined with data collected in 2011.
