We measure the absolute branching fraction for D(0)-->K(-)pi(+) using partial reconstruction of B(0)-->D(+)Xl(-)nu(l) decays, in which only the charged lepton and the pion from the decay D(+)-->D(0)pi(+) are used. Based on a data sample of 230 x 10(6) BB pairs collected at the Upsilon(4S) resonance with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC, we obtain B(D(0)-->K(-)pi(+)) = (4.007+/-0.037+/-0.072)%, where the first uncertainty is statistical and the second is systematic.
我们利用(B(0)\to D(+)Xl(-)\nu(l))衰变的部分重建来测量(D(0)\to K(-)\pi(+))的绝对分支比，其中仅使用来自(D(+)\to D(0)\pi(+))衰变的带电轻子和 pion。基于在 SLAC 的 PEP-II 非对称能量 B 工厂使用 BABAR 探测器在(\Upsilon(4S))共振处收集的(230\times10(6))个(BB)对的数据样本，我们得到(B(D(0)\to K(-)\pi(+)) = (4.007\pm0.037\pm0.072)%)，其中第一个不确定度是统计性的，第二个是系统性的。
