In this site I want to show how to use several computational techniques in Quantum Field Theory. I have been teaching for many years, and I find that this type of information is sometimes difficult to find. I will show how to use Mathematica to calculate traces of Dirac gamma matrices and to do the Lorentz algebra, how to use Fortran or C to do numerics, and how to use other available programs like CalcHEP. For one-loop calculations I have also arranged a web site with many tools. I hope that you find it useful. If you find any mistake please send me an email e-mail:jorge.romao @ tecnico.ulisboa.pt.

WARNING: The Mathematica programs have been tested, for most cases, with Mathematica 12.1 and FeynCalc 9.3. If you find any of these programs not working, please send me an email.
