Study of the doubly and singly Cabibbo suppressed decays D +→K+π+π- and D s+→K+π+π-
Using data collected by the high energy photoproduction experiment FOCUS at Fermilab we study the doubly and singly Cabibbo suppressed decays D+ and Ds+→K+π+π -. Our measurements of Γ(D+→K +π+π-)/Γ(D+→K -π+π+) = 0.0065±0.0008±0. 0004 and Γ(Ds+→K+π +π-)/Γ(Ds+→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 Ds+→K+π+π- mode is performed for the first time. © 2004 Elsevier B.V. All rights reserved.
