Summary: We search for the decay B+ → τ +ντ in a sample of 9.7 million charged B decays taken at the ϒ(4S) using the CLEO detector. To tag this decay, we look at events where one of the charged B's is fully reconstructed and require that the rest of the event be consistent with the other B decaying via B + → τ+ντ. We set an upper limit on the branching fraction (B+ → τ +ντ) < 8.4 × 10–4 at the 90% confidence level.
