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...
BESIII has collected 2.93 and $6.32 fb^{-1}$ of $e^+e^-$ collision data samples at 3.773 and $4.178-4.226~\rm GeV$, respectively. We will report the observation of a new $a_0$ resonance and amplitude analyses of $D_s \to K_S K^+ \pi^0$, $K_S K_S \pi^+$, $\pi^+ \pi^0 \eta^\prime$, $KK3\pi$, $K \pi \pi \pi^0$, and $\pi^+\pi^0\pi^0$. We will also report the transverse polarization determination...
BESIII has collected 2.93 and $6.32~fb^{-1}$ of $e^+e^-$ collision data samples at 3.773 and $4.178-4.226~\rm GeV$, respectively. We will report precision measurements of $f_{Ds}$, $|V_{cs}|$ and test of lepton flavor universality by studying the leptonic decays of $D_s \to l^+\nu$ with $\tau^+ \to \rho^+\nu$, $\pi^+\nu$, and $e^+\nu\nu$. We will also report the studies of $D_s \to \pi^0\pi^0...
With the large datasets on $e^+e^-$-annihilation at the $J/\psi$ and $\psi(3686)$ resonances collected at the BESIII experiment, multi-dimensional analyses making use of polarization and entanglement can shed new light on the production and decay properties hyperon-antihyperon pairs. In a series of recent studies performed at BESIII, significant transverse polarization of the (anti)hyperons...
