摘要：

在这个演示文稿中，我们描述了GoSam（魔像/武士）框架的多粒子散射振幅的自动计算在一个循环的水平。的振幅分析生成的费曼图，并可以使用D维被积函数减少或张量分解进行评估。GoSam可用于计算对标准模型（QCD和EW）过程的单回路修正，并且它可以为超越SM的理论链接通用模型文件。我们展示了GoSam的主要功能，通过其应用程序的几个不同的复杂性的例子。

英文摘要：

In this presentation, we describe the GoSam (Golem/Samurai) framework for the automated computation of multi-particle scattering amplitudes at the one-loop level. The amplitudes are generated analytically in terms of Feynman diagrams, and can be evaluated using either D-dimensional integrand reduction or tensor decomposition. GoSam can be used to compute one-loop corrections to Standard Model (QCD and EW) processes, and it is ready to link generic model files for theories Beyond SM. We show the main features of GoSam through its application to several examples of different complexity.
