Search for the standard model Higgs boson decaying to W+W− in the fully leptonic final state in pp collisions at s=7 TeV

A search for the standard model Higgs boson decaying to W+W− in pp collisions at s=7 TeV is reported. The data are collected at the LHC with the CMS detector, and correspond to an integrated luminosity of 4.6 fb−1. The W+W− candidates are selected in events with two charged leptons and large missing...

Zusammenfassung:	A search for the standard model Higgs boson decaying to W+W− in pp collisions at s=7 TeV is reported. The data are collected at the LHC with the CMS detector, and correspond to an integrated luminosity of 4.6 fb−1. The W+W− candidates are selected in events with two charged leptons and large missing transverse energy. No significant excess of events above the standard model background expectations is observed, and upper limits on the Higgs boson production relative to the standard model Higgs expectation are derived. The standard model Higgs boson is excluded in the mass range 129–270 GeV at 95% confidence level.
