Description
BESIII has accumulated 4.5 fb^-1 of e+e- collision data within the 4.6 and 4.7 GeV energy range, presenting a unique opportunity to investigate Lambda_c+ decays. Our presentation will include the first measurement of the decay asymmetry in the pure W-boson-exchange decay Λ_c^+→Ξ^0 K^+, as well as the study of Lambda_c+ -> Lambda l+ nu and 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+ -> Lambda pi+ pi0, and the latest branching fraction measurements of Cabibbo-suppressed and -favored Lambda_c+ decays, including Lambda_c to p pi0, Sigma- K+ pi+, p eta (omega), and more.
