On the direct CP-violation parameter \(\epsilon'\)

Abstract.

We review different definitions of the \(\epsilon'\) parameter describing direct CP-violation in neutral kaon decays, which was precisely measured in recent experiments, and point out the inconsistency of some of them due to a CPT-constraint. The proper comparison of the experimental results to the theoretical computations is discussed.
