Abstract: 

Lattice Quantum Chromodynamics (QCD) has achieved significant success in addressing various non-perturbative problems in strong interactions. In this presentation, I will review our recent lattice studies on the radiative and weak decavs of charmed hadrons, which are bound by at least one charm quark or anti-charm quark. A highly precise lattice calculation of the radiative decay width of the strange charm meson is presented, which can be utilized to extract the CKM matrix element Vcs by combining with experimental data. A discrepancy in the two-photon decay of charmonium is identified, and we offer insights into the comparison between our findings and experimental measurements.
