Search for the Standard Model Higgs boson in the decay channel H→ZZ (*) →4ℓ with the ATLAS detector

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=7TeV recorded with the ATLAS detector and corresponding to an average integrated luminosity of 2.1fb -1 are compared to the Standard...
