## Abstract

We present the study of CP violation in charm and charmonium decays, using a data sample corresponding to 657 \\times 10^6 BBbar events collected with the Belle detector at the \\Upsilon(4S) resonance at the KEKB asymmetric-energy e^+e^- collider. We report measurements of the polarization fraction and time-dependent CP-violation parameters of the decay B^0\\to D^{\*+}D^{\*-} and of the branching fraction and charge asymmetry in the decay of the Cabibbo- and color-suppressed process B^{\\pm} \\to \\psi(2S) \\pi^{\\pm}.

## 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.
