FeAmGen.jl: A Julia Program for Feynman Amplitude Generation
arXiv:2310.07634 · doi:10.1016/j.cpc.2024.109230
Abstract
FeAmGen.jl is a Julia package designed to generate Feynman diagrams and their corresponding amplitudes for various processes in particle physics. Utilizing the models in the Universal Feynman Output (UFO) format and Qgraf for diagram generation, it also employs SymEngine.jl and Form for amplitude generation. Additionally, the package offers functions for constructing Feynman integral topologies. In conclusion, FeAmGen.jl provides usability and versatility for the high precision calculations of the perturbative quantum field theory in the Standard Model or in the extensions beyond it.
