Description

The BESIII experiment at the Beijing Electron Positron Collider (BEPCII) accumulated the world's largest data sample of $e^{+}{e}^{-}$ collisions at 3.773, 4.009, 4.18 and 4.6 GeV. Based on analyses of leponic and semileptonic decays of $D_{(s)}^{+}$ mesons, we measured CKM matrix elements $|V_{cs(d)}|$, the $D_{(s)}^{+}$ decay constants and the form factors of semi-leptonic $D$ decays. These are important to calibrate the LQCD calculations of decay constant and form factors and to test the CKM unitarity. Using the quantum entangled production of $D^0{\overline{D}}^0$, we determined the strong phase difference and parameters of $D^0{\overline{D}}^0$ mixing.
