Abstract：

I show that theCP-violating asymmetry in K⁰vs K⁰→π⁺π^－π⁰decays differs from that in K_L→π⁺π^－, KL→π⁰π⁰or the semileptonic K_Ltransitions, if there existsCPTviolation in K⁰-K⁰mixing. A delicate measurement of this difference at a super flavor factory (e.g., the φ factory) will provide us with a robust test ofCPTsymmetry in the neutral kaon system.
