Cabibbo-suppressed decays of [Formula Presented]
Using a [Formula Presented] data sample collected with the CLEO II and II.V detectors, we report new branching fraction measurements for two Cabibbo-suppressed decay modes of the [Formula Presented] meson: [Formula Presented] and [Formula Presented] which are significant improvements over past measurements. The errors reflect statistical and systematical uncertainties as well as the uncertainty in the absolute [Formula Presented] branching fraction scale. We also set the first 90% confidence level upper limit on the branching fraction of the doubly Cabibbo-suppressed decay mode [Formula Presented].
