Description
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 in $D^0 \to \omega \phi$, the $K_S/K_L$ asymmetry studies in $D^0 \to K_L X$ ($X = \eta$, $\eta^\prime$, $\omega$ and $phi$), and observation of the new decay mode $D^{*0} \to D^0 e^+ e^-$. In addition, the measurements of the branching fractions of some $D^{0(+)}$ CF and DCS decays will be presented.
