Description
The Belle and Belle$~$II experiments have collected a $1.4~\mathrm{ab}^{-1}$ sample of $e^+e^-$ collision data at centre-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 searches for rare flavour-changing neutral current $c\to u\ell^+\ell^-$ processes in several decay modes. Further, we study several decays of the $\Lambda_c$ and $\Xi_c$ to determine branching fractions, as well as $C\!P$ asymmetries in singly Cabibbo-suppressed decays.
