Abstract

We present the first clear observation of the doubly Cabibbo suppressed decay D⁺ → K^-K⁺K⁺ and the first observation of the singly Cabibbo suppressed decay D_s⁺ → K^-K⁺K⁺. These signals have been obtained by analyzing the high statistics sample of photoproduced charm particles of the FOCUS (E831) experiment at Fermilab. We measure the following relative branching ratios: Γ(D⁺ → K^-K⁺K⁺)/Γ(D⁺ → K^-π⁺π⁺) = (9.49 ± 2.17 ± 0.22) × 10^-4 and Γ(D_s⁺ → K^-K⁺K⁺)/Γ(D_s⁺ → K^-K⁺π⁺) = (8.95 ± 2.12_-2.31^+2.24) × 10^-3, where the first error is statistical and the second is systematic.
