Short description

PHI is a sub-package of the Mathematica package FeynCalc. It adds some tools for manipulating covariant derivatives etc. of effective theories like Chiral Perturbation Theory. Moreover it provides an alternative way of creating coupling definitions for FeynArts. This is convenient if one needs to generate a large number of Feynman rules from different lagrangians.

You may want to download some examples. If you don't have Mathematica, you can still get an idea of what PHI is about by either downloading some of the example notebooks and view them using the Mathematica Player, or by browsing the examples translated to html.

Installation, documentation

As of FeynCalc version 4.1.1, PHI is distributed together with and as a part of FeynCalc. See the file ReadMe.txt.
