Search for the Standard Model Higgs boson decaying to four lepton (muon,   electron) final states with the ATLAS experiment at the LHC collider
  The search for the Standard Model Higgs boson in the four lepton (electron and muon) final state with the ATLAS detector at the LHC is presented. The analysis strategy and the efficiency for selecting the signal and rejecting the background are discussed, focusing on the performance of the lepton identification that can be achieved with the first data of LHC expected in 2008.
