Description
BESIII has accumulated 4.5 fb^-1 of e+e- collision data in the 4.6 and 4.7
GeV energy range, which provides 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+ -> 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+ -> Ξ0 K+, as well as the branching fraction
measurements of the inclusive decays Lambda_c+->X e+ nu and Lambda_cbar-
-> nbar X.
Furthermore, we will present the results of the partial wave analysis of
Lambda_c+ to Lambda pi+ pi0, and Lambda_c+ to Lambda pi+ eta Lambda, Our
presentation will also include branching fraction measurements of
Cabibbo-suppressed decays, including Lambda_c+ to p pi0, and the
measurements of KS-KL asymmetries in the Lambda_c+ decays.
