The Standard Model gives a satisfying description of subatomic processes at low energy (< 1 TeV). Beyond this energy scale, other models must be considered. Supersymmetry is one of them. It gives in an elegant way, solutions to several Standard Model short comings. This document reports the search for a supersymmetric signal characterized by the production of two stops decaying into two b-jets, one electron, one muon and missing energy. This study has been performed at the D0 experiment, located on the ring of Tevatron collider at FermiLab, (Chicago, USA), whose energy in the center of mass reaches {radical}s = 1.96 TeV. The data used for this analysis have been collected during Run IIa of D0 detector; from april 2003 to march 2006 ({approx} 1fb{sup -1}). The objects handled for this analysis require a good understanding of both calorimeters, muon detectors and trackers. As Tevatron is an hadronic collider and the number of Standard Model processes with the same signature as the signal is low, the background is thus dominated by QCD processes. After the selection cuts, no excess of data has been observed with respect to the Standard Model expectation. D0 experiment sensibility has been improved and the 95% …

The first search for exclusive diffractive dijet production with invariant mass {approx}> 100 GeV in Run II of the Fermilab Tevatron Collider is performed. The set of data used is the Run IIa, corresponding to an integrated luminosity of 30 pb{sup -1} of p{bar p} collisions at {radical}s = 1.96 TeV taken with the D0 detector. At 95% CL, an upper limit for the ratio between the number of diffractive exclusive events and the number of non diffractive events is set to be 7.5 x 10{sup -6}, excluding two of the three models proposed to explain this production.

The D0 experiment, located at the Fermilab National Accelerator Laboratory in the US, is used to study proton-anti-proton collisions at a center of mass energy of 1.96 TeV. The experiment's data acquisition system is based on a sophisticated trigger system used to select potentially interesting events. The Level 2 Silicon Track Trigger (L2STT) is part of the trigger system that provides precise reconstruction of charged particle tracks allowing the selection of events that contain the decays of long lived particles. For example, such particles appear in the decay of the Higgs boson into a pair of bottom quarks. The design of the L2STT preprocessor has greatly benefited from recent advances in electronics technology. The preprocessor has been recently installed and will be used to further optimize the triggering strategy of the experiment. Leptoquarks would mediate hypothetical new interactions between the quarks and leptons of the Standard Model. The existence of such particles would be evidence for physics beyond that model. In this thesis, a direct search for leptoquarks is performed in the jets and missing transverse energy final state. For this analysis, a trigger had to be developed along with a tool to precisely determine its efficiency. An analysis of …
