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

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 < mH < 600 GeV. © 2012 SISSA.
