| dc.description.abstract | We report searches for B0→invisible and B0→invisible+γ 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 772×106B¯B pairs and was collected near the Υ(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(B0→invisible)<7.8×10−5 and B(B0→invisible+γ)<1.6×10−5. | es_ES |
