New Results from the BaBar Experiment — •Stefan Spanier — SLAC

The BaBar collaboration has observed a significant CP violation in the neutral B-meson system and is able to search for physics beyond the Standard Model. The experiment is situated at the asymmetric e⁺e⁻ collider, PEP II of the Stanford Linear Accelerator Center (SLAC). More than 120 million B mesons have been collected at the Υ(4S) resonance. This allows for precision studies of lifetime-time dependent properties and for the observation of many rare decays.

A review of the rich physics program of BaBar, which also includes the study of D-mesons, charmed baryons, τ-leptons, and radiative processes will be presented. Emphasis will be placed on measurements of CP violation in the B system.
