About detecting CP-violating processes in J/ψ→ K0-K0 decay

Questions about detecting the CP-violating decay process of J/ψ→ K0K0→KsKs are discussed. Possible background and material regeneration effects are analyzed. The discussion can be directly extended to other vector quarkoniuln decays, like Υ, ψ (2S) and φ→ KsKs.
