Abstract: (APS)
We have searched for the decays B→μν¯μγ and B→eν¯eγ in a sample of 2.7×106 charged B decays collected with the CLEO II detector. In the muon channel, we observe no candidates in the signal region and set an upper limit on the branching fraction of B(B→μν¯μγ)<5.2×10−5 at the 90% confidence level. In the electron channel, we observe five candidates in the signal region and set an upper limit on the branching fraction of B(B→eν¯eγ)<2.0×10−4 at the 90% confidence level.- 13.20.He
