摘要:

我们提出的程序BOKASUN的快速和精确的评估的主积分的两圈自质量日出图的任意值的内部质量和外部的四个动量。我们使用两种方法的组合:伯努利加速级数展开和龙格-库塔数值解的线性微分方程系统。

英文摘要:

We present the program BOKASUN for fast and precise evaluation of the Master Integrals of the two-loop self-mass sunrise diagram for arbitrary values of the internal masses and the external four-momentum. We use a combination of two methods: a Bernoulli accelerated series expansion and a Runge-Kutta numerical solution of a system of linear differential equations.
