Description
BESIII has collected 2.93 and 7.33 $fb^{-1}$ of $e^+e^-$ collision data at 3.773 and 4.128-4.226 GeV, recording the largest dataset of $D\bar{D}$ and $D_sD_s$ pairs in the world, respectively.
We will present the observation of $D^+ \to K_s a^0(980)$ and a new $a^0$-like state with a mass of 1.817 GeV, and the determination of U-spin breaking parameters of the decay $D^0 \to K_L \pi^+ \pi^-$, along with the amplitude analyses of $D^{0(+)} \to 4\pi$ and $D^+ \to K_s\pi^+\pi^0\pi^0$. Our presentation will also include the latest measurements of quantum-correlated $DD$ decays, including the CP-even fraction of $D^0 \to K_s\pi^+\pi^-\pi^0$, $KK\pi\pi$.
We will also present study of $D_s^* \to e \nu$ and the improved measurements of $|Vcs|$ and $D_s$ decay constant in $D_s^+ \to \mu^+ \nu$ and $\tau^+ \nu$. Furthermore, we will present the $D_s \to \eta^{(‘)}$, $D_s \to f^0(980)$, and $D_s \to \phi$ form factor studies.
