  "abstract": "Within the framework of nonrelativistic effective field theory, we calculate the radiative decay widths of the process $X(3872) \\to D\\bar{D} γ$ while taking into account the $D\\bar{D}$ final-state interactions via resonance saturation. The $X(3872)$ is treated as a $D^*\\bar{D} +\\rm c.c.$ bound state with $J^{PC}=1^{++}$. For a representative mixing angle $θ=π/4$, our numerical calculations predict that the tree-level partial decay width for $X(3872) \\to D^0 \\bar{D}^0γ$ can reach approximately $7.3$ keV, while that for $X(3872) \\to D^+ D^- γ$ is less than $1$ keV. It is found that the contribution of the triangle loop diagrams to the total decay width of $X(3872) \\to D^0 \\bar{D}^0γ$ is very small, amounting to less than $1\\%$ of the tree-level result. For the $X(3872)\\to D^+ D^-γ$ decay, the contribution from the triangle loop diagrams is relatively more significant, enhancing the total decay width by roughly $1.3\\%$ relative to the tree-level result. We expect that the present predictions based on the molecular picture of the $X(3872)$ can be tested by future experiments.",
