Measurements of CP Violation, Mixing and Lifetimes of B Mesons with the BaBar Detector

Abstract

We report the observation of CP violation in the $B^0$ meson system. Using a novel technique for time-dependent measurements, we measure a non-zero value for the CP-violating amplitude $\sin 2{\hat{I}}^2$ at the 4.1 $\ddot{I}ƒ$ level. We also report on precision measurements of the $B^{+}$ and $B^0$ lifetimes and the $B^0{\bar{B}}^0$ mixing frequency $\hat{I}”m_d$ obtained with the same technique and on a first measurement of the time-dependent CP-violating amplitude in $B^0\to \ddot{I}{€}^{+}\ddot{I}{€}^{-}$ decays.
