Abstract

Leptonic and semi-leptonic $D$ decays at BESIII contribute the most precise experimental measurement of $|V_{cs(d)}|$ and form factor $f_{D_{(s)}}$ in the world based on 2.93 fb $^{-1}$ and 3.19 fb $^{-1}$ data taken at center-of-mass energies $\sqrt{s} = 3.773$ and 4.180~GeV, respectively. The largest samples at the mass threshold of the charmed hardons $D_{(s)}$ also provide chances to extract form factors of some semi-electronic decays for the first time and together with the semi-muonic decays we could understand lepton flavour universality better.

The International Workshop on the CKM Unitarity Triangle (2018) is a well-established workshop series which provides a venue for theorists and experimentalists to discuss the latest developments in the area of quark flavour physics, and to come up with ideas for improved analyses. This proceeding contains 7 pages and 10 figures
