Search for the higgs boson produced in association with a Z boson and decaying to a pair of bottom quarks with the Atlas experiment at LHC

Alio, Lion 12 November 2014 (has links)
Recherche la Higgs boson produit en associe avec a Z boson et desintegre a paire de b-quarks. Cet etude est realise avec l'experience ATLAS aupres du LHC. Cet recherche contient le travail de l'identification de b-jets au detecteur d'ATLAS, l'etude de triggers de l'energie manquant et introduire un nouveau trigger qui permet de gagner plus de significance de signaux. La recherche de Higgs boson est poursuit avec l'implementation de nouveau trigger et faire d'analyse statistique pour estimer la significance gagne en comparaison avec l'analyse qui utilise triggers nominaux. / Search for the Higgs poson produced in association with a Z boson and decaying to a pair of b-quarks. This study is implemented with the ATLAS experience at LHC. This research includes the work on identification of b-jets in ATLAS detector, study of triggers of missing transverse energy and introduce a new trigger which is expected to gain more signal significance. The search for the Higgs boson is followed with the implementation of the new trigger and do the statistical analysis to estimate the significance gain in comparison with the analysis which use the nominal triggers.
