Abstract : The observation with the ATLAS detector at LHC of a Standard Model Higgs boson produced in association with tt or W bosons, and decaying into WW() and bb final states is reported. In the associated production with top pair, events with Higgs decays to bb and WW() are analyzed, characterized by the presence of b jets and two or three leptons; In the associated production with W boson, events with three leptons in the final state are analyzed.
