Abstract

We have observed the decay mode D0 → KS0KS0. The signal was isolated by detecting both KS0's decaying via KS0 → π+π-, and by using the well-known D*+ → D0 π+ mass difference. We have measured the branching fraction of D0 → KS0KS0 relative to D0 → K+K- and find the ratio Γ(D0 → K0K0)/Γ(D0 → K+K-) to be 0.4 ± 0.3.
