Description
Enhancement of branching fraction and $CP$ violation in $D$ decays would represent a signal of physics beyond the Standard Model. Using the large data sample accumulated by the Belle experiment at KEKB asymmetric energy $e^+ e^−$ collider, we present the results for search for rare $D$ decays such as $D^0 \to \gamma\gamma$, along with the search for $CP$ violation in $D^0 \to V \gamma$ ($V$ = light vector meson) and $D^0 \to K_S^0 K_S^0$.
