Abstract

We search for the decays B-→-ν̄ in a sample of 2.2×106 charged B decays using the CLEO detector. We see no evidence for a signal in any channel and set upper limits on the branching fractions of B(B-→τ-ν̄τ)<2.2×10-3, B(B-→μ-ν̄μ)<2.1×10-5, and B(B-→e-ν̄e)<1.5×10-5 at the 90% confidence level. © 1995 The American Physical Society.
