BABAR Results on CP Violation in the B{sup 0} System

Technical Report ·
DOI:https://doi.org/10.2172/812943· OSTI ID:812943

The BABAR detector, operating at the SLAC PEP-II asymmetric B Factory, has collected a sample of 32 million B{bar B} pairs by May 2001, at energies close to the {Upsilon}(4S) resonance. The measurement of sin2{beta} = 0.59 {+-} 0.14(stat) {+-} 0.05(syst), performed with a study of time-dependent CP-violating asymmetries in neutral B decays, establishes CP violation at the 4{sigma} level. In addition, preliminary results on CP-violating asymmetries in the decay channel B{sup 0} {yields} {pi}{sup +}{pi}{sup -} are presented.
