MADGRAPH 5是MADGRAPH矩阵元素生成器的新版本，用Python编程语言编写。它实现了许多新的、高效的算法，在程序的各个方面提供了改进的性能和功能。它有一个新的用户界面，几个新的输出格式，包括PYTHIA 8的c++进程库，以及完全兼容FEYNRULES的新物理模型实现，允许以拉格朗日形式编写的任何模型的事件生成。MADGRAPH 5建立在与之前版本相同的理念之上，它的设计允许它被用作一个协作平台，在这个平台上可以开发理论、现象学和模拟项目，然后分发给高能社区。我们描述了代码的思想和最重要的发展，并通过几个简单的现象学示例说明了它的功能。
MADGRAPH 5 is the new version of the MADGRAPH matrix element generator, written in the Python programming language. It implements a number of new, efficient algorithms that provide improved performance and functionality in all aspects of the program. It features a new user interface, several new output formats including C++ process libraries for PYTHIA 8, and full compatibility with FEYNRULES for new physics models implementation, allowing for event generation for any model that can be written in the form of a Lagrangian. MADGRAPH 5 builds on the same philosophy as the previous versions, and its design allows it to be used as a collaborative platform where theoretical, phenomenological and simulation projects can be developed and then distributed to the high-energy community. We describe the ideas and the most important developments of the code and illustrate its capabilities through a few simple phenomenological examples.
