Description
The study of weak radiative decays of charmed mesons is still in its developing stage. The weak decays of $D$ mesons pose challenges due to significant final-state interactions. However, decays mediated by $c \rightarrow u \gamma$ transitions can be affected by potential contributions coming from the non-minimal supersymmetry, which is an new physics scenario. The ratio of branching fractions for radiative $D^{0}$ decays could be violated already in the SM framework, while a similar ratio for $D_{s}^{+}$ radiative decays offers much better prospects for new physics. We present herein the first sensitivity study of the radiative charm decays $D_{s}^{+}\rightarrow \rho^+ \gamma$ and $D_{s}^{+} \rightarrow K^{*+} \gamma$ with data collected by the Belle experiment.
