摘要: I present here a selection of preliminary results on charmed hadron decays from BESIII collaboration, including the study of D+→K−π+e+νe, the measurement of the form factors in D+→ωe+νe and the search for D+→ϕe+νe, the study of decay dynamics and \emph{CP} asymmetry in D+→K0Le+νe, and the measurements of the absolute branching fractions of twelve Cabbibo-favored hadronic $\lambdacp$ decay modes and Λ+c→Λe+νe. The results are based on the data samples collected with the BESIII detector at the ψ(3770)peak and at central-of-mass energy of 4.599~GeV.
