| Abstract | Data from the CPLEAR collaboration coupled with the assumption that the BellSteinberger relation holds have provided direct evidence for T violation. In this note we investigate what we can say about T violation without such an assumption. We show that both the modulus and the phase of η+− can be reproduced with T invariant dynamics through finetuning CPT breaking. The large T odd correlation observed by the KTeV collaboration in KL → ππee thus does not yield direct evidence for T violation. In such a world the phase of ǫ ′ ǫ is δ2 − δ0 − φSW ∼ −(85.5±4)◦. Also, K → ππ could exhibit a CPT asymmetry of up to few×10−3 without upsetting any known bound. |
