用整体拟合从包含衰变B -> Xc l nu确定|V_cb|

Determination of |V_cb| from Inclusive Decays B -> Xc l nu using a Global Fit

Christoph Schwanda

摘要:

本文综述了包含半轻子B介子衰变B -> Xclnu的理论和实验研究现状。在此基础上,给出了重味平均组(HFAG)对Cabibbo-Kobayashi-Maskawa矩阵元|V_cb|和b夸克质量m_b的最新测定结果.

英文摘要:

In this article, we review the theory and the experimental status of inclusive semileptonic B meson decays B -> Xc l nu. Based on these inputs, we present the latest determination of the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element |V_cb| and of the b-quark mass m_b, obtained by the Heavy Flavor Averaging Group (HFAG).
