Search for K S 0 invisible decays
- Abstract:
- Based on (1.0087 ± 0.0044) × 1010J/ψ events collected with the BESIII detector at the BEPCII e+e− storage ring, we search for KS0 invisible decays via the J/ψ →ϕKS0KS0 process. No significant signal is observed, and the upper limit of the branching fraction of these invisible decays is set at 8.4 × 10−4 at the 90% confidence level. This is the first experimental search for KS0 invisible decays.
