A bstractWe present standard model (SM) estimates for exclusive c → uγ processes in heavy quark and hybrid frameworks. Measured branching ratios ℬD0→ϕK¯∗0γ$$ \mathrm{\mathcal{B}}\left({D}^0\to\ \left(\phi, {\overline{K}}^{\ast 0}\right)\gamma \right) $$ are at or somewhat exceeding the upper range of the SM and suggest slow convergence of the 1/mD, αsexpansion. Modelindependent constraints on ΔC =  ΔU  = 1 dipole operators from ℬ(D0 → ρ0γ) data are obtained. Predictions and implications…
