Abstract

Using data from the FOCUS (E831) experiment at Fermilab, we present a new measurement of the branching ratio for the Cabibbo-favored decay mode D 0 → K-K-K+π+. From a sample of 143 ± 19 fully reconstructed D0 → K -K-K+π+ events, we measure Γ(D0 → K-K-K+π +)/Γ(D0 → K-π-π +π+) = 0.00257 ± 0.00034(stat.) ± 0.00024(syst.). A coherent amplitude analysis has been performed to determine the resonant substructure of this decay mode. This analysis reveals a dominant contribution from φ and Kο*0(892) states.
