報(bào)告摘要：
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 decays 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.
