Studies of CP violation in B→J/ψK* decays
CP violation in B→J/ψK* decays is studied using an angular analysis in a data sample of 253fb-1 recorded with the Belle detector at the KEKB e+e- collider. The flavor separated measurements of the decay amplitudes indicate no evidence for direct CP violation. T-odd CP violation is studied using the asymmetries in triple product correlations, and the results are consistent with the standard model null predictions. The time-dependent angular analysis gives the following values of CP-violating parameters: sin 2 1=0.24±0.31±0.05 and cos 2 1=0.56±0.79±0.11. © 2005 The American Physical Society.
