摘要

本文报道了QCD中2环阶和3环阶大量算子矩阵元的双质量校正的最新结果。这些修正构成了可变风味数方案的组成部分。由于粲子质量和底夸克质量的值相似，双质量修正形成了一个重要的贡献。

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

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.
