全阶多尺度五边形积分

Multiscale pentagon integrals to all orders

Dhimiter D. Canko, Costas G. Papadopoulos, Nikolaos Syrrakos

摘要:

我们提出了一个循环的五点主积分与多达三个的壳腿的分析结果。采用正则微分方程方法和简化微分方程方法。所有必要的边界条件给出封闭的形式,导致解决方案的Goncharov多项式的任意重量。将呈现权重高达六的显式结果。

英文摘要:

We present analytical results for one-loop five-point master integrals with up to three off-shell legs. The method of canonical differential equations along with the Simplified Differential Equations approach is employed. All necessary boundary terms are given in closed form, resulting to solutions in terms of Goncharov Polylogarithms of arbitrary weight. Explicit results up to weight six will be presented.
