Description
The Charmed baryon is a unique system, considered as a bound state of a charm quark and a light di-quark due to the suppression of the color spin interaction of the heavy charm quark. Belle experiment has led the charmed baryon spectroscopy with the world highest integrated luminosity $e^+e^-$ collision data provided by KEKB accelerator. In this talk, we present the latest results on charmed baryons from Belle including absolute branching fraction of $\Lambda_c \to pK^-\pi^+$, first observation of doubly Cabbibo suppressed decay of $\Lambda_c^{+}$, precise measurement of the mass and width of excited $\Xi_c$ baryons, and those decays into $\Lambda D$ final states.
