费曼图自动生成的一种简单算法

A simple algorithm for automatic Feynman diagram generation

Bo Xiao, Hao Wang, Shou-hua Zhu

摘要:

提出了一种费曼图自动生成的算法。该算法直接从FD的定义公式出发,概念简单,易于编码。每个FD的对称因子是自然生成的。希望能为研究新的计算技术或制作新的计算工具的研究人员以及研究有效场论的研究人员带来方便。本文还介绍了一个由该算法编制的C语言程序,该程序简短、快速、通用性强:它接收任意用户定义的模型和任意过程作为输入,生成任意阶的FD。

英文摘要:

An algorithm for the automatic Feynman diagram (FD) generation is presented in this paper. The algorithm starts directly from the definition formula of FD, and is simple in concept and easy for coding. The symmetry factor for each FD is naturally generated. It is expected to bring convenience for the researchers who are studying new calculation techniques or making new calculation tools and for the researchers who are studying effective field theory. A C-program made from the algorithm is also presented, which is short, fast, yet very general purpose: it receives arbitrary user defined model and arbitrary process as input and generates FD's at any order.
