It's been awhile, but wasn't that all broken with kaon decay?

- vagab0nd 5y agoNo, that broke the CP symmetry, not CPT.
- HappySweeney 5y agoLayman here: doesn't violating one imply a violation of the other?
- vagab0nd 5y agoDisclaimer: I'm not an expert either. I don't think so. CP violation means if you flip charge and parity, you can tell the difference (the Kaon experiment). But if you flip charge, parity and time all at the same time, so far there's no experiment that says you can tell the difference (CPT symmetry). In fact, it is my understanding that CPT invariance + broken time symmetry implies broken CP symmetry.
