Abstract：
I show that the CP-violating asymmetry in K⁰ vs K⁰→π⁺π^－π⁰ decays differs from that in K_L→π⁺π^－, KL→π⁰π⁰ or the semileptonic K_L transitions, if there exists CPT violation in K⁰-K⁰ mixing. A delicate measurement of this difference at a super flavor factory (e.g., the φ factory) will provide us with a robust test of CPT symmetry in the neutral kaon system.
