Abstract

We report the observation of the doubly Cabibbo-suppressed decay D⁺ → K⁺π^-π⁺ in data from Fermilab charm hadroproduction experiment E791. With a signal of 59 ± 13 events we measured the ratio of the branching fraction for this mode to that of the Cabibbo-favored decay D⁺ → K^-π⁺π⁺ to be B(D⁺ → K⁺π^-π⁺) / B(D⁺ → K^-π⁺π⁺) = (7.7 ± 1.1 ± 0.8) × 10^-3. A Dalitz plot analysis was performed to search for resonant structures.
