Abstract: Motivated by the experimental measurements of D0 radiative decay modes, we have proposed a model to study the D0K*0γ decay, by establishing a link with D0K*0V (V=ρ0, ω) decays through the vector meson dominance hypothesis. In order to do this properly, we have used the Lagrangians from the local hidden gauge symmetry approach to account for Vγ conversion. As a result, we have found the branching ratio B[D0K*0γ]=(1.55-3.44)×10-4, which is in fair agreement with the experimental values reported by the Belle and BaBar collaborations.
