Abstract
Branching ratios and upper limits at 90% confidence level for D+ and D -s(+) --> K+ pi(-) pi(+) decays collected in Fermilab photoproduction experiment E-687 are reported. The D+ results are: Gamma(D+ --> K+ <pi (>)-pi(+))/Gamma(D+ --> K- pi(+)pi(+)) = (7.2 +/- 2.3 +/- 1.7) x 10(-3 ), Gamma(D+ --> K(0)(892)pi(+))/Gamma(D+ --> K- pi(+)pi(+)) < 0.0021, and Gamma(D+ K(+)rho(0)(770))/Gamma(D+ --> K- pi(+)pi(+)) < 0.0067. T he D-s(+) results are: Gamma(D-s(+) --> K(+)pi(-)pi(+))/Gamma(D-s(+) - -> phi(1020)pi(+)) = 0.28 +/- 0.06 +/- 0.05, Gamma(D-s(+) -->K(0) (89 2)pi(+))/Gamma(D-s(+) --> phi(1020)pi(+)) = 0.18 +/- 0.05 +/- 0.04, an d Gamma(D-s(+) --> K+ rho(0)(770))/Gamma(D-s(+) --> phi(1020)pi(+)) < 0.08.
