Abstract
We measure the branching fraction for the Cabibbo-suppressed decay and search for violation via a measurement of the asymmetry as well as the -odd triple-product asymmetry . We use of data recorded by the Belle experiment, which ran at the KEKB asymmetric-energy collider. The branching fraction is measured relative to the Cabibbo-favored normalization channel ; the result is , where the first uncertainty is statistical, the second is systematic, and the third is from uncertainty in the normalization channel. We also measure , and . These results show no evidence of violation.
