Abstract

We present a measurement of the branching fraction for the doubly-Cabibbo-suppressed decay

D^{+} \to K^{+} π^{0}

, using

281 {pb}^{- 1}

of data accumulated with the CLEO-c detector on the

ψ (3770)

resonance. We find

B (D^{+} \to K^{+} π^{0}) = (2.28 \pm 0.36 \pm 0.15 \pm 0.08) \times 10^{- 4}

, where the first uncertainty is statistical, the second is systematic, and the last error is due to the uncertainty in the reference mode branching fraction.
