Recherche du squark bottom se désintégrant en cascade dans l'expérience D0 auprès du Tevatron. Elaboration d'un format condensé de données.

Abstract : ppbar interactions at s^1/2 = 1.96 TeV are studied using the D0 detector at the Tevatron collider. Verifying the supersymmetric extension of the Standard Model is a part of the physics program. In this framework, the decay of the lightest supersymmetric partner of the b-quark giving rise to two electrons, two jets and missing transverse energy in the final state is searched for, using an integrated luminosity of 42.6 pb-1. The result is interpreted within the mSUGRA framework, one of the supersymmetric models.
Prior to this analysis a software called Thumbnail has been developed which allows the storage of the complete set of real and simulated data on disk. The code is integrated into the official software releases of the DO collaboration.
