Descrição: We report the observation of the doubly Cabibbo-suppressed decay <math>D^+\to K^+ \pi^- \pi^+\,\!</math> in data from Fermilab charm hadroproduction experiment E791. With a signal of 59 <math>\pm\,\!</math> 13 events we measured the ratio of the branching fraction for this mode to that of the Cabibbo-favored decay <math>D^+\to K^- \pi^+ \pi^+\,\!</math> to be <math>B(D^+ \to K^+ \pi^- \pi^+) / B(D^+ \to K^- \pi^+ \pi^+) =\,\!</math> <math>(7.7 \pm 1.7 \pm 0.8) \times 10^{-3}.\,\!</math> A Dalitz plot analysis was performed to search for resonant structures.
