QEDFeynmanDiagrams.jl
This project is dedicated to generating Feynman diagrams for scattering processes in perturbative QED. It is part of the QEDjl-project and relies on QEDcore.jl. Furthermore, it can generate code to compute the matrix element for scattering processes, using ComputableDAGs.jl and RuntimeGeneratedFunctions.jl.
For example usage, see the n-photon Compton or trident pages.
The inner workings of the project are explained in the manual.
