Abstract
We report an improved measurement of the partial-rate CP asymmetry in [Formula Presented] decays. The analysis is based on a data sample of [Formula Presented] [Formula Presented] pairs collected at the [Formula Presented] resonance with the Belle detector at the KEKB [Formula Presented] storage ring. We measure [Formula Presented] where the first and second errors are statistical and systematic, respectively; the corresponding 90% confidence-level interval is [Formula Presented] © 2003 The American Physical Society.
