Overview of Charm Physics at Belle and Belle II

The Belle and Belle II experiments have collected large samples of [Formula: see text] collision data at center-of-mass energies near the [Formula: see text] resonance, containing a substantial number of [Formula: see text] events. We report measurements of [Formula: see text]–[Formula: see text] mixing parameters using a model-independent analysis of [Formula: see text] decays. We also present results on [Formula: see text] asymmetries in [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] decays. All measured [Formula: see text] asymmetries are consistent with zero within uncertainties. In addition, recent results on branching fractions of charmed-baryon decays, including several [Formula: see text] decay modes, are discussed.
