About Detecting CP-Violating Processes in $J/ψ\to \KzKzb $ Decay

Abstract

Questions about detecting CP-violating decay process of $J/ψ\to K^0\bar{K}^0\to K_SK_S$ are discussed. Possible background and material regeneration effect are analyzed. The discussion can be directly extended to other vector quarkonium decays, like $Υ$, $ψ(2S)$ and $ϕ\to K_S K_S$.
