WebFeynArts. FeynArts is a Mathematica package for the generation and visualization of Feynman diagrams and amplitudes. It started out in 1990 as a Macsyma code written by Hagen Eck and Sepp Küblbeck which could produce tree-level and one-loop diagrams in the Standard Model [Kü90], but soon got ported to the Mathematica platform. In 1995, Hagen ... WebNov 19, 2015 · The "standard" way to install FeynArts+FormCalc on OSX or Linux would be to use the automatic installation script from the developer.
