Charmed baryon decays at BESIII

BESIII has accumulated 6.4~fb${}^{-1}$ of $e^{+}{e}^{-}$ collision data at center-of-mass energies from 4.60 to 4.95~GeV, corresponding to the world’s largest sample of ${\mathrm{\Lambda }}_c^{+}{\bar{\mathrm{\Lambda }}}_c^{-}$ pairs. This proceeding summarizes recent BESIII results on charmed baryon decays, including the first observation of the transverse polarization of the ${\mathrm{\Lambda }}_c^{+}$ in $e^{+}{e}^{-}\to {\mathrm{\Lambda }}_c^{+}{\bar{\mathrm{\Lambda }}}_c^{-}$, a precision measurement of the inclusive decay ${\mathrm{\Lambda }}_c^{+}\to \mathrm{\Lambda }X$, the first observations of ${\mathrm{\Lambda }}_c^{+}\to n{e}^{+}{\nu }_e$ and ${\mathrm{\Lambda }}_c^{+}\to n{\pi }^{+}\eta$ with deep-learning techniques, the first observation of ${\mathrm{\Lambda }}_c^{+}\to p{K}^{-}{e}^{+}{\nu }_e$ together with evidence for ${\mathrm{\Lambda }}_c^{+}\to {\mathrm{\Sigma }}^{\pm }{\pi }^{\mp }{e}^{+}{\nu }_e$, and partial wave analyses of ${\mathrm{\Lambda }}_c^{+}\to \mathrm{\Lambda }{\pi }^{+}\eta$.
