套调和和的结构关系

Structural Relations between Nested Harmonic Sums

Johannes Bluemlein

摘要:

本文描述了在可重正化规范场理论中,直到3圈水平的物理单尺度量描述中出现的套调和和之间的结构关系。这些是权重{ \sf w=6}谐波和。我们确定通用的基本功能,可以描述一大类的物理量,并推导出其复杂的分析。对于3圈QCD Wilson系数,需要35个基本函数,而15个基本函数的子集描述了3圈异常维度。

英文摘要:

We describe the structural relations between nested harmonic sums emerging in the description of physical single scale quantities up to the 3--loop level in renormalizable gauge field theories. These are weight {\sf w=6} harmonic sums. We identify universal basic functions which allow to describe a large class of physical quantities and derive their complex analysis. For the 3--loop QCD Wilson coefficients 35 basic functions are required, whereas a subset of 15 describes the 3--loop anomalous dimensions.
