Abstract: (arXiv)

We report a search for

B^{0}

decays into invisible final states using a data sample of

657 \times 10^{6}

B\bar{B}

pairs collected at the

\Upsilon(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 \times 10^{-4}

at the 90% confidence level for the branching fraction of invisible

B^{0}

decay.
