This Letter presents a search for the Standard Model Higgs boson in the decay channel H→ZZ(⁎)→ℓ+ℓ−ℓ′+ℓ′−, where ℓ,ℓ′=e or μ, using proton–proton collisions at s=7 TeV recorded with the ATLAS detector and corresponding to an integrated luminosity of 4.8 fb−1. The four-lepton invariant mass distribution is compared with Standard Model background expectations to derive upper limits on the cross section...
A search for the Standard Model Higgs boson in the decay channel H→ZZ(⁎)→ℓ+ℓ−ℓ′+ℓ′−, where ℓ=e,μ, is presented. Proton–proton collision data at s=7 TeV recorded with the ATLAS detector and corresponding to an average integrated luminosity of 2.1 fb−1 are compared to the Standard Model expectations. Upper limits on the production cross section of a Standard Model Higgs boson with a mass between 110...
