我们报告了使用 772 x 10(6) B (B) 条对上的数据样本测量 B+ -> tau(+) nu(tau) 衰变的分支分数，这些数据样本是在 KEKB 不对称能量 e(+)e(-) 对撞机上与 Belle 探测器的 Upsilon(4S) 共振处收集的。我们在半轻衰变中重建伴随的 B 介子，并检测衰变通道 B+ -> tau(+) nu(tau) 中的反冲 B 候选者。我们获得 B(B+ -> tau(+) nu(tau)) = [1.25 +/- 0.28(stat.) +/- 0.27(syst.)] x 10-(4) 的分支分数。该结果与之前的测量以及基于标准模型的计算的预期非常吻合。
We report a measurement of the branching fraction of B+ -> tau(+) nu(tau) decays using a data sample of 772 x 10(6) B (B) over bar pairs, collected at the Upsilon(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 recoiling B candidate in the decay channel B+ -> tau(+) nu(tau). We obtain a branching fraction of B(B+ -> tau(+) nu(tau)) = [1.25 +/- 0.28(stat.) +/- 0.27(syst.)] x 10-(4). This result is in good agreement with previous measurements and the expectation from the calculation based on the Standard Model.
