A Test of CPT Symmetry in K^0 vs \bar{K}^0 to π^+π^-π^0 Decays

Abstract

I show that the CP-violating asymmetry in K^0 vs \bar{K}^0 \to π^+π^-π^0 decays differs from that in K_L \to π^+π^-, K_L \to π^0π^0 or the semileptonic K_L transitions, if there exists CPT violation in K^0-\bar{K}^0 mixing. A delicate measurement of this difference at a super flavor factory (e.g., the ϕfactory) will provide us with a robust test of CPT symmetry in the neutral kaon system.
