Abstract
We have studied the (Formula presented) and (Formula presented) decays using a 20.7 (Formula presented) data set collected with the BABAR detector. We observe a signal of (Formula presented) (Formula presented) events and determine the ratio (Formula presented) to be (Formula presented) The CP-violating charge asymmetries for the (Formula presented) and (Formula presented) decays are determined to be (Formula presented) and (Formula presented). © 2002 The American Physical Society.
