MaRTIn – Massive Recursive Tensor Integration

We present MaRTIn, an extendable all-in-one package for calculating amplitudes up to two loops in an expansion in external momenta or using the method of infrared rearrangement. Renormalisable and non-renormalisable models can be supplied by the user; an implementation of the Standard Model is included in the package. In this manual, we discuss the scope and functionality of the software, and give instructions of its use.

我们推出MaRTIn，一款可扩展的一体化工具包，支持通过外动量展开或红外重排（infrared rearrangement）方法计算至多两圈级的散射振幅。用户可自定义提供可重整化（renormalisable）与不可重整化（non-renormalisable）模型，本工具包内置标准模型（Standard Model）的实现方案。本手册将阐述该软件的适用范围与功能，并提供使用指南。
