Abstract

Branching ratios and upper limits at 90% confidence level for D+ and Ds+ → K+π-π+ decays collected in Fermilab photoproduction experiment E-687 are reported. The D+ results are: Γ(D+ → K+π-π+) Γ(D+ → K-π+π+) = (7.2 ± 2.3 ± 1.7) × 10-3, Γ(D+ → K*0(892)π+) Γ(D+ → K-π+π+) < 0.0021, and Γ(D+ → K+ρ{variant}0(770)) Γ(D+ → K-π+π+) < 0.0067. The Ds+ results are: Γ(Ds+ → K+π-π+) Γ(Ds+ → Φ(1020)π+) = 0.28 ± 0.06 ± 0.05, Γ(Ds+ → K*0(892)π+ Γ(Ds+ → Φ(1020)π+) = 0.18 ± 0.05 ± 0.04, and Γ(Ds+ → K+ρ{variant}0(770)) Γ(Ds+ → Φ(1020)π+) < 0.08.
