Abstract
After a description of the apparatus (muons chambers, hadronic calorimeter, a central tracking detector and an electromagnetic calorimeter using BGO crystals), a theoretical and phenomenological approach of the Standard Model requiring the existence of the Higgs boson, is presented. The Higgs search is carried out through the e{sup +}e{sup -} {yields} He{sup +}e{sup -} process, which distinctive signature is the presence of 2 energetic and well separated electrons coming from Z{sup 0*} isolated from a-coplanar hadronic jets (Higgs decay product). Building different selections optimised for the Higgs mass range is examined, and the analyses are mainly based on multiplicity and electromagnetic isolation criteria with cuts on the sum of the total transverse momentum of electrons. The conclusion of this thesis is the limit given by He{sup +}e{sup -} channel on the standard Higgs mass, M{sub H} superior to 29 GeV.
