Observation of CP Violation in the B0 System
- SLAC
The BABAR detector, operating at energies near the {Upsilon}(4S) resonance at the PEP-II asymmetric B Factory at SLAC, has collected a sample of 32 million B{bar B} pairs by May 2001. A study of time-dependent CP-violating asymmetries in events where one neutral B meson is fully reconstructed in a final state containing charmonium has resulted in the measurement sin2{beta} = 0.59 {+-} 0.14 (stat) {+-} 0.05 (syst), which establishes CP violation in the B{sup 0} meson system at the 4{sigma} level. B lifetime and mixing measurements from a sub-sample of 23 million B{bar B} pairs are also presented.
