Abstract

The latest results on the direct experimental search for a Standard Model Higgs boson decaying to a pair of Z bosons are presented. Three distinct final states are considered: H→ ZZ^(*)→ ℓℓℓℓ, H→ ZZ→ ℓℓνν, and H→ ZZ→ ℓℓ qq, where ℓ = e, μ. A dataset of more than 1fb^-1 of proton-proton collisions at √(s) = 7 TeV collected by the ATLAS detector at the CERN LHC during the on-going 2011 run is used. In this model and for these final states, Higgs boson masses in the ranges 192 GeV < m_H < 196 GeV, 214 < m_H < 222 GeV, and 340 < m_H < 460 GeV have been excluded at the 95% confidence level.
