具有两条重线的双圈交叉六线主积分

On a two-loop crossed six-line master integral with two massive lines

T. Huber

摘要:

本文用维数正则化方法计算了两重线的双圈交叉六线顶点主积分,并给出了D-4中有限部分的结果。我们专注于特别是纯分析计算的边界条件,我们来自一个三重梅林-巴恩斯表示。我们还描述了如何计算的边界条件是用来获得三个非平凡的关系之间的调和多项式的第六根单位。

英文摘要:

We compute the two-loop crossed six-line vertex master integral with two massive lines in dimensional regularisation, and give the result up to the finite part in D-4. We focus in particular on the purely analytical calculation of the boundary condition which we derive from a three-fold Mellin-Barnes representation. We also describe how the computation of the boundary condition is used to derive three non-trivial relations among harmonic polylogarithms of the sixth root of unity.
