Abstract
Using data from the FOCUS experiment (FNAL-E831), we report on the decay of D-0 mesons into final states containing more than one K-S(0). We present evidence for two Cabibbo favored decay modes, D-0 --> K(S)(0)K(S)(0)K(-)pi(+) and D-0 --> K(S)(0)K(S)(0)K(+)pi(-), and measure their combined branching fraction relative to D-0 --> (K) over bar (0)pi(+)pi(-) to be Gamma(D-0-->K(S)(0)K(S)(0)K(+/-)pi(+/-))/Gamma(D-0-->K(0)pi(+)pi(-)) = 0.0106 +/- 0.0019 +/- 0.0010. Further, we report new measurements of Gamma(D-0-->(KSKSKS0)-K-0-K-0)/Gamma(D-0-->K(0)pi(+)pi(-)) = 0.0179+/-0.0027+/-0.0026, Gamma(D-0-->K-0(K) over bar (0))/Gamma(D-0-->(K) over bar (0)pi(+)pi(-)) = 0.0144+/-0.0032+/-0.0016, and Gamma(D-0-->(KSKSKS0)-K-0-K-0)Gamma(D-0-->(K) over bar (0)pi(+)pi(-)) = 0.0208+/-0.0035+/-0.0021 where the first error is statistical and the second is systematic.
