$|V_{cs(d)}|$ measurements and LFU tests in charm leptonic decays
BESIII collected 2.93 fb$^{−1}$, 0.482 fb$^{−1}$, 3.19 fb$^{−1}$, and 0.567 fb$^{−1}$ of data samples at the center of-mass energies $\sqrt{s}$ = 3.773, 4.009, 4.178, and 4.6 GeV, respectively. Herein, we report the improved measurements of the quark mixing matrix elements $|V_{cs(d)}|$ by using $D$...
