CP Violation in the KS → π+π-π° Decay

The failure of CP-invariance observed in K° → ππ can be represented by a single complex number1 ∈ ≃ 2.3e/4 (assuming CPT-invariance2), and is compatible with the “standard model”. However there is no evidence for a CP failure except in the K° → ππ channel, and the known failure could just as well be caused by a super-weak, Δs = 2, interaction as by some pecularity of the standard model.
