Branching ratios of the decays
D0 -> K0bar K0 and
D0 -> Ks0 Ks0 Ks0
by P.L. Frabetti et al.
Abstract.
The branching ratios of D0 --> K0 K0 and
D0 --> Ks0 Ks0 Ks0 relative to
D0 --> K0 pi+ pi- are reported.
The data were accumulated in the 1990-1991 fixed target
running period
of the Fermilab high energy
photoproduction experiment E687.
Gamma(D0 --> K0 K0)/
Gamma(D0 --> K0 pi+ pi-)
is measured to
be 0.039 +- 0.013 +- 0.013 and
Gamma(D0 --> Ks0 Ks0 Ks0)/
Gamma(D0 --> K^0 pi+ pi-) is measured
to be 0.035 +- 0.012 +- 0.006.
We also measure
Gamma(D0 --> K0 pi+ pi-)/
Gamma(D0 --> K- pi+) to be
1.61 +- 0.10 +- 0.15.
