AbstractAbstract
[en] The plan of this manuscript follows my research path over the past 10 years: the muon identification and common analysis tools at D0, the measurement of the inclusive production of W boson decaying into muon and top quark studies. In the first section, I describe my work about muon identification, certification of the standard muon identification criteria, measurement of the muon selection efficiency and about the development of common analysis format and tools. In the second section, I explain how these efficiency measurements can be used to measure the inclusive W boson production cross section in the muon channel. The W → μν cross section measurement can be seen as a standard candle to establish several analysis pieces that have to be put in place to perform more complex measurements like top quark analyses. In the last section I introduce more extensively the top quark physics at the Tevatron and describe in more details the main analyses in the dilepton channel I was involved in: the measurement of the tt-bar inclusive cross section in the dilepton channel as well as the ratio of cross sections, the measurement of the top quark mass in the dilepton channel, the extraction of the mass from the tt-bar cross section and the Tevatron top quark mass combination. Before concluding, I finish the section with the description of the latest results on the tt-bar charge asymmetry both at the Tevatron and at the LHC. (author)

Le plan de ce manuscrit suit mon parcours de recherche des 10 dernieres annees: l'identification des muons et les outils d'analyse communs a D0, la mesure de la production inclusive du boson W se desintegrant en muons et l'etude des quarks top. Dans la premiere section, je decris mon travail sur l'identification des muons, la certification des criteres standards d'identification des muons, la mesure de l'efficacite de la selection des muons et le developpement d'un format et d'outils d'analyse communs. Dans la deuxieme section, j'explique comment ces mesures d'efficacite peuvent etre utilisees pour mesurer la section efficace inclusive de production de bosons W dans le canal du muon. La mesure de la section efficace W → μν peut etre consideree comme une chandelle standard permettant d'etablir plusieurs elements d'analyse qui doivent etre mis en place pour effectuer des mesures plus complexes comme les analyses des quarks top. Dans la derniere section, j'introduis plus en detail la physique des quarks top au Tevatron et decris plus en detail les principales analyses dans le canal dilepton dans lesquelles j'ai participe: la mesure de la section efficace inclusive tt-bar dans le canal dilepton ainsi que le rapport des sections efficaces, la mesure de la masse du quark top dans le canal du dilepton, l'extraction de la masse de la section efficace tt-bar et la combinaison de masse du quark top du Tevatron. Avant de conclure, je termine la section avec la description des derniers resultats sur l'asymetrie de charge tt-bar au Tevatron et au LHCOriginal Title

AbstractAbstract
[en] Recent Run 2 experimental results on electroweak physics from the CDF and D0 collaborations at Tevatron are reviewed. They present measurements of the inclusive W and Z boson cross-sections times leptonic branching ratio as well as the Z/γ* forward-backward asymmetry and the W± charge asymmetry for p(bar p) collisions at √s = 1.96 TeV. The first Run 2 studies for the W width and W mass measurements are also reported. The di-boson production results are presented elsewhere

AbstractAbstract
[en] To achieve a high level of discrimination between nuclear recoils and radioactive background, a new in size 320 g ionization-heat bolometer has been designed and realized for the EDELWEISS experiment. With this new device we are expecting a great improvement in background limitation in particular for betas and low-energy X- and γ-rays. Sensitivities to Luke effect and infrared source are also discussed

AbstractAbstract
[en] The authors review the field of top-quark physics with an emphasis on experimental techniques. The role of the top quark in the Standard Model of particle physics is summarized and the basic phenomenology of top-quark production and decay is introduced. They discuss how contributions from physics beyond the Standard model could affect the top-quark properties or event samples. The many measurements made at the Fermilab Tevatron, which test the Standard model predictions or probe for direct evidence of new physics using the top-quark event samples, are reviewed here.

AbstractAbstract
[en] A measurement of the top-antitop (t anti t) charge asymmetry is presented using data corresponding to an integrated luminosity of 4.6 fb"-"1 of LHC pp collisions at a centre-of-mass energy of 7 TeV collected by the ATLAS detector. Events with two charged leptons, at least two jets and missing transverse momentum are selected. Two charge asymmetry observables are studied, based on the identified charged leptons, A"l"l_C, or on the reconstructed t anti t final state, A"t "a"n"t"i "t_C. The asymmetries are measured to be: A"l"l_C =0.024±0.015(stat.)±0.009(syst.), A"t "a"n"t"i "t_C=0.021±0.025(stat.)±0.017(syst.). The measured values are in agreement with the Standard Model predictions.
