We report a search for B0 decays into invisible final states using a data sample of 657×106 BB¯ pairs collected at the ?(4S) resonance with the Belle detector at the KEKB e+e- collider. The signal is identified by fully reconstructing a hadronic decay of the accompanying B meson and requiring no other particles in the event. No significant signal is observed, and we obtain an upper limit of 1.3×10-4 at the 90% confidence level for the branching fraction of invisible B0 decay.
