Abstract

We present a measurement of time-dependent [Formula presented] asymmetries and an updated determination of the [Formula presented]-odd fraction in the decay [Formula presented] using a data sample of [Formula presented] pairs collected by the BABAR detector at the PEP-II [Formula presented] Factory at SLAC. We determine the [Formula presented]-odd fraction to be [Formula presented]. The time-dependent [Formula presented] asymmetry parameters [Formula presented] and [Formula presented] are determined to be [Formula presented] and [Formula presented], respectively. The standard model predicts these parameters to be [Formula presented] and 1, respectively, in the absence of penguin diagram contributions. © 2003 The American Physical Society.
