## Abstract

The Belle detector at KEKB has collected 6.2 fb^{-1} of data at the Upsilon(4S) resonance. Presented here are preliminary measurements, from this data sample, of sin(2phi\_1) and other quantities relating to CP.

## 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.
