TL;DR
This paper reports initial results from the BABAR experiment, including measurements of CP violation, B meson lifetimes, and mixing, based on data collected at the SLAC collider in 1999-2000.
Contribution
First analysis of CP violation and B meson properties using early BABAR data at SLAC, providing preliminary measurements relevant to the Standard Model.
Findings
Preliminary sin2beta measurement: 0.12 +/- 0.37 (stat) +/- 0.09 (syst)
B meson lifetime measurements
B0-B0bar mixing results
Abstract
The BABAR detector at the SLAC PEP-II asymmetric e+e- collider has first started collecting data in May 1999. A study of time-dependent CP-violating asymmetries in B0 --> J/psi K0S and B0 --> psi(2S) K0S decays has been performed on a data sample of 9.0fb-1 taken at the Y(4S) resonance and 0.8fb-1 off-resonance, collected through July 2000. The preliminary result sin2beta = 0.12+/-0.37 (stat) +/- 0.09 (syst) is presented here, together with preliminary results on neutral and charged B meson lifetimes and B0B0bar mixing.
