## Abstract

We report recent measurements of the CKM angle phi\_1/beta using large data samples collected by the Belle and BaBar experiments at the e^+ e^- asymmetric-energy colliders.

## 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.
