## Abstract

The hypothesis of sigma meson pole dominance in the Delta I = 1/2 K -\> pi pi amplitudes is tested by using the K\_L-K\_S mass difference.

## 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.
