Measurements of CP Violation, Mixing and Lifetimes of B Mesons with the BaBar Detector
- SLAC
We report the observation of CP violation in the B{sup 0} meson system. Using a novel technique for time-dependent measurements, we measure a non-zero value for the CP-violating amplitude sin2{beta} at the 4.1 {sigma} level. We also report on precision measurements of the B{sup +} and B{sup 0} lifetimes and the B{sup 0}{bar B}{sup 0} mixing frequency {Delta}m{sub d} obtained with the same technique, and on a first measurement of the time-dependent CP-violating amplitude in B{sup 0} {yields} {pi}{sup +}{sup -} decays.
