Abstract
We report measurements of branching fractions for charged and neutral [Formula presented] decays where the [Formula presented] meson is reconstructed in the [Formula presented], [Formula presented], [Formula presented], and [Formula presented] decay channels. The neutral [Formula presented] channel is a [Formula presented] eigenstate and can be used to measure the [Formula presented] violation parameter [Formula presented]. We also report the first observation of the [Formula presented] mode. The results are based on an analysis of [Formula presented] of data collected by the Belle detector at KEKB. © 2003 The American Physical Society.
