Search for $B^0$ Decays to Invisible Final States ($+\gamma$) at Belle

Belle Collaboration, Y. Ku, P. Chang +153

We report searches for $B^0\to \mathrm{invisible}$ and $B^0\to \mathrm{invisible}+\gamma$ decays, where the energy of the photon is required to be larger than 0.5 GeV. These results are obtained…
