Description
BESIII has accumulated 4.5 $fb^{-1}$ of e+e- collision data in the 4.6 and 4.7 GeV energy range, which provide the largest dataset of $\Lambda_c^- \Lambda_c^+$ pairs in the world.
We will present a novel way for exploring CP violation using the $\Lambda_c^- \Lambda_c^+$ threshold data and the first observation of the transverse polarization of $\Lambda_c^+$ in the reaction $e^+e^-\to \Lambda_c^+ \Lambda_c^-$.
Furthermore, Our presentation will also include the observation of a rare beta decay of the charmed baryon $\Lambda_c^+ \to n e^+ \nu$ with a Graph Neural Network, recent results of the partial wave analysis of $\Lambda_c^+$, as well as the branching fraction measurements of the inclusive decays $\Lambda_c^+ \to X e^+ \nu$ and $\Lambda_c^- \to \bar{n} X$.
