Abstract
We present measurements of the branching fractions for the Cabbibo suppressed decays D+->pi(+)pi(0) and D+-> K+pi(0) based on a data sample corresponding to an integrated luminosity of 124.3 fb(-1). The data were taken with the BABAR detector at the PEP-II B Factory operating on and near the Upsilon(4S) resonance. We find B(D+->pi(+)pi(0))=(1.25 +/- 0.10 +/- 0.09 +/- 0.04)x10(-3) and B(D+-> K+pi(0))=(2.52 +/- 0.47 +/- 0.25 +/- 0.08)x10(-4), where the first uncertainty is statistical, the second systematic and the last error is due to the uncertainties in the absolute branching fraction scale for D+ mesons. This represents the first observation of the doubly Cabibbo-suppressed D+-> K+pi(0) decay mode and a new measurement of the D+->pi(+)pi(0) branching fraction.
