Charmed baryon decays at BESIII

BESIII has accumulated 4.5 fb$^{-1}$ of $e^+e^-$ collision data in the 4.6 to 4.7 GeV energy range, corresponding to the world's largest sample of $\Lambda_c^+\bar{\Lambda}_c^-$ pairs. This paper summarizes recent BESIII results on charmed-baryon decays, including the observation of the rare semi-leptonic decay $\Lambda_c^+\to ne^+\nu_e$ using a Graph Neural Network, the first measurement of the decay asymmetry in the pure $W$-exchange decay $\Lambda_c^+\to\Xi^0K^+$, and branching fraction measurements of the inclusive decays $\Lambda_c^+\to Xe^+\nu_e$ and $\bar{\Lambda}_c^-\to \bar{n}X$. We also report partial wave analyses of $\Lambda_c^+\to\Lambda\pi^+\pi^0$ and $\Lambda_c^+\to\Lambda\pi^+\eta$, measurements of Cabibbo-suppressed decays such as $\Lambda_c^+\to p\pi^0$, and studies of $K_S^0-K_L^0$ asymmetries in $\Lambda_c^+$ decays.
