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+-->pi(+)pi(0))=(1.31+/-0.17+/-0.09+/-0.09)x10(-3) and B(D+-->K+(K) over bar (0))=(5.24+/-0.43+/-0.20+/-0.34)x10(-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(+)pi(0))<4.2x10(-4).
