Description
BESIII has collected $4.5 fb^{-1}$ of $e^+e^-$ collision data between 4.6000 and $4.6999~\rm GeV$. This unique data offers ideal opportunity to determine absolute branching fractions of $\Lambda_c^+$ decays. We will report the first observation of $\Lambda_c^+ \to n\pi^+$. Meanwhile, we will report prospect on the studies of semileptonic and the other hadronic decays of $\Lambda_c^+$ in the near future.
