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. 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--> Lambda_c+ Lambda_cbar-. Furthermore, Our presentation will also include the observation of a rare beta decay of the charmed baryon Lambda_c+ -> 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+->X e+ nu and Lambda_cbar- -> nbar X.
