This paper reviews results of beyond-the-standard model searches at the Tevatron presented in a plenary talk at the Europhysics Conference on High Energy Physics (EPS-HEP) in Grenoble. Here I present a selection of results from the CDF and D0 experiments that were shown at the conference during the parallel sessions. Much more is available and can be found at the experiment's web pages. This proceeding essentially focuses on searches in the dilepton, diboson, and t-tbar final states. Throughout the paper, hints of new physics observed at the Tevatron are also briefly discussed.
This paper presents an overview of recent experimental direct searches for Higgs-boson and beyond-the-standard-model (BSM) physics shown in the plenary session at the SUSY07 conference. The results reported correspond to an integrated luminosity of up to 2 fb-1 of Run II data from $p\bar{p}$ collisions collected by the CDF and D0 experiments at the Fermilab Tevatron Collider. Searches covered include: the standard model (SM) Higgs boson (including sensitivity projections), the minimal supersymmetric extension of the standard model (MSSM), charged Higgs bosons and extended Higgs models, supersymmetric decays that conserve R-parity, gauge-mediated supersymmetric breaking models, long-lived particles, leptoquarks, extra gauge bosons, extra dimensions, and finally signature-based searches. Given the excellent performance of the collider an...
The energy frontier is currently at the Fermilab Tevatron accelerator, which collides protons and antiprotons at a center-of-mass energy of 1.96 TeV. The luminosity delivered to the CDF and D0 experiments has now surpassed the 4 fb−1. This paper reviews the most recent direct searches for Higgs bosons and beyond-the-standard-model (BSM) physics at the Tevatron. The results reported correspond to an integrated luminosity of up to 2.5 fb−1 of Run II data collected by the two Collaborations. Searches covered include: the standard model (SM) Higgs boson (including sensitivity projections), the neutral Higgs bosons in the minimal supersymmetric extension of the standard model (MSSM), charged Higgs bosons and extended Higgs models, supersymmetric decays that conserve or violate R-parity, gauge-mediated supersymmetric breaking models, long-li...

Ce mémoire d'HDR présente une synthèse des travaux que j'ai effectués depuis 7 ans pour la préparation de l'expérience D0 à Fermilab et l'analyse des données du collisionneur à hadrons Tevatron. Il présente deux thématiques principales : système de déclenchement et recherche de nouvelle physique, notamment la recherche de particules supersymétriques et du boson de Higgs du modèle standard.
