Description
The Belle and Belle II experiments have collected a $1.6~\mathrm{ab}^{-1}$ sample of $e^+e^-$ collision data at center-of-mass energies near the $\Upsilon(nS)$ resonances. These samples contain a large number of $e^+e^-\to c\bar{c}$ events that produce charmed mesons and baryons. We present new results including the observation of the radiative decay $D_s(2317)^+ \to D_s^* \gamma$, a search for the electroweak penguin decay $D^+\to \pi^+ e^+e^-$, and a partial-wave analysis of the decay $\Xi_c^+\to \Xi^-\pi^+\pi^+$. Direct $C\!P$ violation is searched for in $D^0\to \pi^+\pi^-\pi^0$ decays and $D^+\to \pi^+\pi^0$ decays. We also present results on $C\!P$ violation in the charm baryon decays $\Xi^+_c\to \Sigma^+h^+ h^-$ and $\Lambda_c^+\to ph^+ h^-$.
