## Abstract

Using a more accurate approximation than that applied by Lee--Oehme--Yang we show that the interpretation of the tests measuring the difference between the $K\_{0}$ mass and the ${\\bar K}\_{0}$ mass as the CPT--symmetry test is wrong. We find that in fact such tests are tests for the existence of the hypothetical interaction allowing the first order $\|\\Delta S\| = 2$ transitions $K\_{0} \\rightleftharpoons {\\bar K}\_{0}$.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
