FZJ Physical review / D Physical review / D APS Melville, NY 2470-0010 10.1103/PhysRevD.105.L051101 English L051101 5 105 We present a search for the decays of B0 mesons into a final state containing a Λ baryon and missing energy. These results are obtained from a 711  fb−1 data sample that contains 772×106  B¯B pairs and was collected near the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. We use events in which one B meson is fully reconstructed in a hadronic decay mode and require the remainder of the event to consist of only a single Λ. No evidence for these decays is found, and we set 90% confidence level upper limits on the branching fractions in the range 2.1–3.8×10−5. This measurement provides the world’s most restrictive limits, with implications for baryogenesis and dark matter production. ISSN 2470-0029 not unique: **3 hits**.
