Abstract

Using a 13.7 fb^-1 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 D⁺ meson: B(D⁺→ π⁺π⁰) = (1.31±0.17±0.09±0.09) ×10^-3 and B(D⁺→ K⁺K̄ ⁰) = (5.24±0.43±0.20±0.34)×10^-3 which are significant improvements over past measurements. The errors reflect statistical and systematical uncertainties as well as the uncertainty in the absolute D⁺ branching fraction scale. We also set the first 90% confidence level upper limit on the branching fraction of the doubly Cabibbo-suppressed decay mode B(D⁺ → K⁺π ⁰)<4.2×10^-4.
