Search for the rare decay $D^0\to \gamma \gamma$ at Belle

Belle Collaboration, N. K. Nisar, G. B. Mohanty +180

We search for the rare radiative decay $D^0\to \gamma \gamma$ using a data sample with an integrated luminosity of $832\mathrm{f}{\mathrm{b}}^{-1}$ recorded by the Belle detector at the KEKB $e^{+}{e}^{-}$ asymme…
