Abstract

Using data collected by the high energy photoproduction experiment FOCUS at Fermilab we study the doubly and singly Cabibbo suppressed decays D⁺ and D_s⁺→K⁺π⁺π ^-. Our measurements of Γ(D⁺→K ⁺π⁺π^-)/Γ(D⁺→K ^-π⁺π⁺) = 0.0065±0.0008±0. 0004 and Γ(D_s⁺→K⁺π ⁺π^-)/Γ(D_s⁺→K ⁺K^-π⁺) = 0.127±0.007±0.014 are based on samples of 189±24 D⁺ and 567±31 D _s⁺ reconstructed events, respectively. We also present Dalitz plot analyses of the two decay channels; the amplitude analysis of the D_s⁺→K⁺π⁺π^- mode is performed for the first time.
