Search for a heavy Standard Model Higgs boson in the channel H→ZZ→ℓ + ℓ - qq̄ using the ATLAS detector

A search for a heavy Standard Model Higgs boson decaying via H→ZZ→ℓ + ℓ - qq̄, where ℓ=e, μ, is presented. The search is performed using a data set of pp collisions at √s=7 TeV, corresponding to an integrated luminosity of 1.04 fb -1 collected in 2011 by the ATLAS detector at the CERN LHC collider....
