A search for the Standard Model Higgs boson in the decay channel $H\rightarrow ZZ^{(∗)} \rightarrow l+l−l'+l'−$, where $l,l' = e,\mu$, using proton-proton collisions at $sqrt{s}=7$ and 8 TeV recorded with the ATLAS detector is presented. The four lepton invariant mass distribution is compared with Standard Model background expectations to derive upper limits on the cross section of a Standard Model Higgs boson with a mass between 110 GeV and 600 GeV.
