GoSam：自动单循环计算程序
GoSam: A program for automated one-loop Calculations
摘要：
本文介绍了多粒子过程单圈振幅的自动计算程序包GoSam。振幅是根据费曼图生成的，并且可以使用D维积分级分解或张量约简或两者的组合来约简。GoSam可以用来计算QCD和电弱理论的单圈修正，也可以链接标准模型之外的理论的模型文件。一个标准的接口程序计算实际辐射也包括在内。通过实例说明了该程序的灵活性。
英文摘要：
The program package GoSam is presented which aims at the automated calculation of one-loop amplitudes for multi-particle processes. The amplitudes are generated in terms of Feynman diagrams and can be reduced using either D-dimensional integrand-level decomposition or tensor reduction, or a combination of both. GoSam can be used to calculate one-loop corrections to both QCD and electroweak theory, and model files for theories Beyond the Standard Model can be linked as well. A standard interface to programs calculating real radiation is also included. The flexibility of the program is demonstrated by various examples.
