Description
BESIII has collected 2.93, 7.33, and 4.5 fb^-1 of $e^+e^-$ collision data samples at 3.773, 4.128-4.226, and 4.6-4.7 GeV, which provide the largest dataset of $D\bar{D}$, $D_s^*D_s$, and $\Lambda_c\bar{\Lambda}_c$ pairs in the world, respectively.
For charmed mesons, we will report the updated measurements of $D_s^+\to \eta^{(‘)} e^+ \nu_e$, $D_s^+\to \tau^+ \nu_\tau$, and the form factor studies in $D_s^+\to\pi^+\pi^- e^+ \nu_e$. In addition, we will report the amplitude analyses of Cabibbo-favored and -suppressed $D_s$ decays, including the observation of a new a_0-like state at 1.817 GeV. We will also report the improved measurement of the strong-phase difference in quantum-correlated $D\bar{D}$ decays.
For charmed baryon, we will report the form factor measurement in $\Lambda_c^+ \to \Lambda e^+ \nu_e$, the observation of $\Lambda_c^+\to p K^- e^+ \nu_e$, and branching fraction measurements of $\Lambda_c$ singly-Cabibbo-suppressed decays.
