Abstract

We report a search for the rare decays B→h(*) νν̄, where h(z.ast;) stands for K+, KS0, K*+, K*0, π+, π0, ρ+, ρ0 and p. The results are obtained from a 711 fb-1 data sample that contains 772×106BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB e+e- collider. We search for signal candidates by fully reconstructing a hadronic decay of the accompanying B meson and requiring a single h(*) meson left on the signal side. No significant signal is observed and we set upper limits on the branching fractions at 90% confidence level. The measurements of B+→K *+νν̄, B+→π +νν̄, B0→π0νν̄ and B0→ρ0ν ν̄ provide the world's currently most restrictive limits.
