Le vide de l'infiniment petit à l'infiniment grand : un point de vue expérimental

Abstract : The void, from its nature and its role in the description of phenomena in the infinity small as well as the infinity big, works as a link to introduce the different experimental works presented in this manuscript. From the infinity small, the preparation of the new physics search beyond the standard model of particle physics is exposed with the liquid argon calorimeter prototype for the ATLAS experiment. Then the search for supersymmetry with R-Parity violation with the ALEPH detector is presented. Next, the standard model of cosmology is detailed with the appearance of the mysterious dark energy which is at the origin of the current acceleration of our universe. This acceleration can be measured thanks to the supernova observations of the SNLS survey that is presented with its different steps : supernova search then cosmological parameters and type Ia supernova explosion rate measurements.
