Measurement of the CP-Violating Asymmetry Amplitude sin2beta with the BaBar Detector
Shahram Rahatlou
Abstract
We present updated results on time-dependent CP-violating asymmetries in neutral B decays to several CP eigenstates. The measurements use a data sample of about 62 million Y(4S) --> B Bbar decays collected between 1999 and 2001 with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We measure sin2beta = 0.75 +/- 0.09 (stat) +/- 0.04 (syst) and |lambda| = 0.92 +/- 0.06 (stat) +/- 0.02 (syst).
