Symbolic calculations using Mathematica

Nowadays mathematica is a required tool for any Physicist. For High Energy Physics there are several packages, like FeynArts, FeynCalc and FeynRules

• FeynArts
  This is a program for drawing Feynman diagrams. It can be obtained from http://www.feynarts.de.

• FeynCalc
  This is a very ambitious program, that does the Dirac and Lorentz algebra, but also calculates processes at one-loop. It is designed to have FeynArts as input. It can be obtained from https://feyncalc.github.io.
  A good place to find the documentation is https://github.com/FeynCalc/feyncalc/wiki/Documentation
  To install follow the instructions here.

  I have prepared one notebook Examples.nb that summarizes a number of different programs. To work all the programs must exist in the same directory.
  For convenience you can find here a zip of all the programs needed to run Examples.nb.

  Warning:
  Some of the scripts were done for older versions of FeynCalc. I have upgraded and tested most of them to work with FeynCalc 9.3.0 (as of May 2020). If you find any problem please let me know so that I can update the file.

• FeynRules
  It is normally a non-trivial task to have a complete set of Feynman rules for a given theory. There as today several programs that aim at doing that.
  One such package for mathematica is the program FeynRules written by N. Christensen and C. Duhr. It can be obtained from http://feynrules.irmp.ucl.ac.be.
