深度非弹性散射中的双质量三圈效应

Two-mass three-loop effects in deep-inelastic scattering

J. Ablinger, J. Blümlein, A. De Freitas, A. Goedicke, C. Schneider, K. Schönwald

摘要:

本文报道了QCD中二圈和三圈阶大质量算符矩阵元的双质量修正的最新结果。这些校正形成了可变风味数方案的构建块。由于粲夸克质量和底夸克质量的相似值,双质量修正形成了重要的贡献。

英文摘要:

We report on recent results on the two-mass corrections for massive operator matrix elements at 2- and 3-loop orders in QCD. These corrections form the building blocks of the variable flavor number scheme. Due to the similar values of the charm and bottom quark masses the two-mass corrections form an important contribution.
