PHI adds tools to FeynCalc for manipulating covariant derivatives etc. of effective theories like Chiral Perturbation Theory. Moreover, PHI provides an alternative way of creating coupling definitions for FeynArts – convenient for generating a large number of Feynman rules from different Lagrangians.
This is mostly a … Read the rest
