Search for B-0 decays to invisible final states ( plus gamma) at Belle
Original language description
We report searches for B-0 -> invisible and B-0 -> invisible +gamma decays, where the energy of the photon is required to be larger than 0.5 GeV. These results are obtained from a 711 fb(-1) data sample that contains 772 x 10(6)B (B) over bar pairs and was collected near the Upsilon(4S) resonance with the Belle detector at the KEKB e(+)e(-) collider. We observe no significant signal for either decay and set upper limits on their branching fractions at 90% confidence level of B(B-0 -> invisible) < 7.8 x 10(-5) and B(B-0 -> invisible + gamma) 1.6 x 10(-5).
