Abstract
We report the first observation of the Cabibbo-suppressed decays , and , using a data sample of collected at the resonance with the Belle detector at the KEKB asymmetric-energy collider. We measure the ratios of branching fractions to be , and , where the first uncertainty is statistical and the second is systematic.
