Study of the decay mode D-0 - K-K-K+pi(+)

摘要

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+ pi(+). From a sample of 143 +/- 19 fully reconstructed D-0 --> K- K- K+ pi(+) events, we measure Gamma(D-0 --> K- K- K+ pi(+))/Gamma(D-0 --> K- pi(-) pi(+) pi(+)) = 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 phi and (K) over bar*(0)(892) states.
