Rare Charm Decays at Belle II

Belle II detector, situated at the SuperKEKB $$e^{+}e^{-}$$ accelerator, will collect 50 times larger data sample than the Belle detector. This will allow more precise measurements and tests of the Standard Model (SM). Flavor Changing Neutral Current (FCNC) processes are forbidden at the tree level in the SM. However, there are several new physics (NP) models that can enhance the branching fractions of the FCNC. $$D^{0} \rightarrow \gamma \gamma $$ is one such decay mode sensitive to the NP searches. We will discuss the prospects for charm rare decays at Belle II, focusing on the $$D^{0} \rightarrow \gamma \gamma $$ decay mode. Further, we will also demonstrate the capability of the Belle II detector by reconstructing the charm mesons from the neutral candidates ( $$D^{0} \rightarrow K_\textrm{S}^{0}\pi ^{0}$$ ). The study uses the most recently collected data by the Belle II detector corresponding to an integrated luminosity of 34.6 fb $$^{-1}$$ .
