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

Abstract

A search is reported for the standard model Higgs boson in the H → ZZ → ℓ+ℓ−τ +τ − 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 significant deviation from the background expectation. An upper limit four to twelve times larger than the predicted value is set at 95% confidence level for the product of the standard model Higgs boson production cross section and decay branching fraction in the mass range 190 < m H < 600 GeV.
