Search for a Standard Model Higgs boson in the mass range 200–600 GeV in the H→ZZ→ℓ + ℓ − qq¯ decay channel with the ATLAS Detector

A search for a heavy Standard Model Higgs boson decaying via H→ZZ→ℓ + ℓ − qq¯, where ℓ=e or μ, is presented. The search uses a data set of pp collisions at s=7 TeV, corresponding to an integrated luminosity of 4.7 fb −1 collected in 2011 by the ATLAS detector at the CERN LHC. No significant excess o...
