摘要:

本文报道了B原子无粲半轻子衰变$B \to X_{u} \ell ν$的测量结果。分析利用强子标记,并进行了贝尔实验的完整数据集,包括7.72亿$B\bar{B}$对。在诉讼中,部分分支分数和CKM矩阵元素$|V_{ub}|$的测量的初步结果。

英文摘要:

We report on the measurement of inclusive charmless semileptonic B decays $B \to X_{u} \ell ν$. The analysis makes use of hadronic tagging and is performed on the full data set of the Belle experiment comprising 772 million $B\bar{B}$ pairs. In the proceedings, the preliminary results of measurements of partial branching fractions and the CKM matrix element $|V_{ub}|$ are presented.
