Abstract
Branching ratios and upper limits at 90% confidence level for D+ and Ds+ → K+pi−pi+ decays collected in Fermilab photoproduction experiment E-687 are reported. The D+ results are: G(D+->K+pi-pi+)/G(D+->K-pi+pi+)=(7.2+-2.3+-1.7)10(-3), G(D+->K*0(892)pi+)/G(D+->K-pi+pi+)<0.0021, and G(D+->K+ rho0(770))/G(D+->K-pi+pi+)<0.0067. The D(s)+ results are: G(D(s)+->K+pi-pi+)/G(D(s)+->phi(1020)pi+) = 0.28+-0.06+-0.05, G(D(s)+->K*0(892)pi+)/G(D(s)+->phi(1020)pi+)=0.18+-0.05+-0.04, and G(D(s)+->K+ rho0(770))/G(D(s)+->phi(1020)pi+)<0.08
