Aspects de la violation de la symétrie CP dans BABAR. Contraintes sur la matrice CKM

Abstract : This document presents the work done within the BABAR Collaboration as well as a phenomenological study on the interpretation of the B measurements related to the Unitarity Triangle. The read-out electronics of the Cerenkov detector, the DIRC, and especially the Time-Digital-Converter designed at LPNHE are described. Two major results of the BABAR Collaboration are presented: the measurement of the sin2β parameter in the b → ccs modes, which has established the CP violation in the B sector in 2001 and the study of CP asymetries in the B0 → π+π− channel. The constraints on the Unitarity Triangle from the K0K0 system, the B semi-leptonic decays, the B oscillation parameters are in excellent agreement with those from sin2β et α.
