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+ +0) = (1.310.170.090.09) 10-3 and B(D+ K+K 0) = (5.240.430.200.34)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+ 0)<4.210-4. 2004 The American Physical Society.
