We report a measurement of the branching fraction of B+ → τ+ντ decays using a data sample of 772 × 106BB pairs, collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e collider. We reconstruct the accompanying B meson in a semileptonic decay and detect the B+ → τ+ντ candidate in the recoiling event. We obtain a branching fraction of B(B+ → τ+ντ) = [1.25 ± 0.28(stat.) ± 0.27(syst.)] × 10−4. This result is in good agreement with previous measurements and the expectation from calculations based on the Standard Model.
