Abstract

Relative branching fractions of [Formula: see text] decays (where h, h′ = K or π) and the direct CP asymmetry [Formula: see text] in the [Formula: see text] mode are measured with 179 ± 11 pb -1 of data collected at [Formula: see text] using the CDF II detector at the Fermilab Tevatron [Formula: see text] collider. The first branching-fraction measurement of a [Formula: see text] meson to two pseudoscalars, [Formula: see text], and a search for the baryon mode [Formula: see text] are also presented, in addition to branching-fraction limits on the rare channels [Formula: see text], [Formula: see text], and [Formula: see text].
