The B(0) lifetime was measured with a sample of 23 million BB pairs collected by the BABAR detector at the PEP-II e(+)e(-) storage ring during 1999 and 2000. Events from the semileptonic decay B(0)-->D(-)l(+)nu(l) have been selected with a partial reconstruction method in which only the charged lepton and the slow pi from the D--->D(0)pi(-) decay are reconstructed. The result is tau(B(0)) = 1.529+/-0.012(stat)+/-0.029(syst) ps.
B(0)寿命是通过BABAR探测器在1999年至2000年期间于PEP-II正负电子存储环收集的2300万个BB对样本进行测量的。通过部分重建方法选择了来自半轻子衰变B(0)→D(-)l(+)ν(l)的事例，其中仅重建了带电轻子和来自D→D(0)π(-)衰变的慢π介子。结果为τ(B(0)) = 1.529±0.012(统计)±0.029(系统)皮秒。
