Recherche du boson de Higgs du modele standard dans le canal de pp{bar}ZH -> e+e-b{bar}, avec le détecteur D0 auprès du TeVatron à Fermilab.

Abstract : The Higgs boson is the missing piece of the particle physics standard model and it is therefore intensively searched for. This thesis presents the work performed for this search at low mass (100-150 GeV) in the ZH -> e+e-b{bar} channel, with 4.2 fb-1 of D0 data. First, the theoretical and experimental parts are described. Then my studies are elaborated for the identification of the electrons, in particular in the inter-cryostat region of the detector. Finally, the analysis for the Higgs search is presented in details and the obtained limits on the Higgs production cross section are given.
