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 $c\to u\gamma$ 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 $D_s^{+}\to {\rho }^{+}\gamma$ and $D_s^{+}\to K^{\ast +}\gamma$ with data collected by the Belle experiment.
