Abstract
We report the observation of the doubly Cabibbo-suppressed decay D+ -- > K(+)pi(-)pi(+) in data from Fermilab charm hadroproduction experimen t 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- pi(+)pi(+) to be B(D+ --> K(+)pi(-)pi(+)) / B(D+ --> K(-)pi (+)pi(+)) = (7.7 +/- 1.7 +/- 0.8) x 10(-3). A Dalitz plot analysis was performed to search for resonant structures. (C) 1997 Published by El sevier Science B.V.
