Abstract

Abstract

En 中文
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.
Keywords:
Loop calculation
Perturbation theory
Momentum expansion
