Search for the standard model Higgs boson in the H → ZZ → l+l-ꚍ+ꚍ- decay channel in pp collisions at √s = 7 TeV

A search is reported for the standard model Higgs boson in the H → ZZ → l+l-ꚍ+ꚍ- decay mode, where l = µ or e, in proton-proton collisions at √s = 7TeV, corresponding to an integrated luminosity of 4.7 fb-1 collected with the CMS detector at the LHC. No evidence is found for a signi_cant deviation f...

Descripción
Sumario:A search is reported for the standard model Higgs boson in the H → ZZ → l+l-ꚍ+ꚍ- decay mode, where l = µ or e, in proton-proton collisions at √s = 7TeV, corresponding to an integrated luminosity of 4.7 fb-1 collected with the CMS detector at the LHC. No evidence is found for a signi_cant deviation from the background expectation. An upper limit four to twelve times larger than the predicted value is set at 95% con_dence level for the product of the standard model Higgs boson production cross section and decay branching fraction in the mass range 190 < mH < 600 GeV.
