This package contains two programs. trace computes traces of products of gamma matrices. FeynmanParameter converts integrals over momentum space of the type encountered in ...

This paper describes the Mathematica package FeynArts used for the generation and visualization of Feynman diagrams and amplitudes. The main features of version 3 are: ...

We present two Mathematica programs, FeynmanParameter and trace, that automate the evaluation of Feynman diagrams with loops. FeynmanParameter converts integrals over loop ...

The paper describes the included package TamarA for analytical calculation of Feynman diagram expressions. The package supports both relativistic and non-relativistic three ...

The Feynman Path Integral is a way of calculating the quantum-mechanical propagator G( xb, tb, xa, ta ), which gives the probability amplitude for a particle at position xb ...

FeynArts is a Mathematica package for the generation and visualization of Feynman diagrams and amplitudes. The current version 3 features a completely new rendering engine ...

For the investigation of higher order Feynman integrals, potentially with tensor structure, it is highly desirable to have numerical methods and automated tools for ...

We present a recursive diagrammatic method for evaluating tree-level Feynman diagrams involving multi-fermions which interact through gauge bosons (gluons or photons). Based ...

In this paper the C++ version of FIRE is presented — a powerful program performing Feynman integral reduction to master integrals. All previous versions used only Wolfram ...

We introduce the Mellin-Barnes representation of general Feynman integrals and discuss their evaluation. The Mathematica package AMBRE has been recently extended in order to ...
