Abstract

We present the recent results on charm baryon production and decays at Belle and Belle II experiments using a 1.4 ab$^{-1}$ data sample of $e^+ e^-$ collision collected at center-of-mass energies near the $\Upsilon(nS)$ resonances. The collected data contain a large number of $e^+ e^- \to c \bar{c}$ events that produce charmed baryons. We report on several studies of the $\Lambda_c$ and $\Xi_c$ decays to determine their branching fractions.
