About detecting CP-violating processes in J/ψ→K～0K～0 decay

【摘要】：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 quarkonium decays, like Υ, ψ(2S) and φ→KSKS.
