Description
BESIII has accumulated 4.5 $fb^{-1}$ of e+e- collision data within the 4.6 and 4.7 GeV energy range, which provide the largest dataset of $\Lambda_c - \Lambda_c$ pairs in the world.
Our presentation will include the observation of a rare beta decay of the charmed baryon $\Lambda_c^+ \to n e^+ \nu$ with a Graph Neural Network and the first measurement of the decay asymmetry in the pure W-boson-exchange decay $\Lambda_c^+ \to \Xi^0 K^+$, as well as the branching fraction measurements of the inclusive decays $\Lambda_c^+ \to X e^+ \nu$ and $\bar{\Lambda_c}^- \to \bar{n} X$.
Furthermore, we will present the results of the partial wave analysis of $\Lambda_c^+ \to \Lambda \pi^+ \pi^0$, and $\Lambda_c^+ \to \Lambda \pi^+ \eta$. Our presentation will also include branching fraction measurements of Cabibbo-suppressed decays, including $\Lambda_c^+ \to p \pi^0$, and the measurements of $K_S-K_L$ asymmetries in the $\Lambda_c^+$ decays.
