FeynRules – Feynman rules made easy

Abstract
In this paper we present FeynRules, a new Mathematica package that facilitates the implementation of new particle physics models. After the user implements the basic model information (e.g., particle content, parameters and Lagrangian), FeynRules derives the Feynman rules and stores them in a generic form suitable for translation to any Feynman diagram calculation program. The model can then be translated to the format specific to a particular Feynman diagram calculator via FeynRules translat...

### 程序名称：FeynRules
### 目录编号：AEDI_v1_0

#### 摘要
本文介绍FeynRules——一款可简化新型粒子物理模型实现流程的Mathematica软件包。用户录入模型的基础信息（如粒子组成、参数及拉格朗日量(Lagrangian)）后，FeynRules将自动推导费曼规则(Feynman rules)，并将其以通用格式存储，该格式可适配任意费曼图(Feynman diagram)计算程序的转换需求。后续可通过FeynRules的转换模块，将模型转换为特定费曼图计算器所需的专属格式（原文此处截断为translat...）。

#### 问题本质
实现从拉格朗日量自动推导费曼规则，并将新型模型集成至蒙特卡洛事件生成器与FeynArts中。
