摘要:

本文报道了B → X_s γ中粲夸克质量相关矩阵元的NNLO QCD修正计算的最新进展。特别强调的是新的结果的虚拟O(α_s^2)费米子的贡献,这些矩阵元素[1]。

英文摘要:

Recent developements in the calculation of the NNLO QCD corrections to the charm quark mass dependent matrix elements in B -> X_s gamma are reported. Special emphasis is put on the new results of the virtual O(alpha_s^2) fermionic contribution to these matrix elements [1].
