Nature of problem:
Feynman-diagrammatic computations in field theory.

Solution method:
FeynArts works in three steps: (1) creation of the topologies, (2) insertion of fields into the topologies, (3) application of the Feynman rules to produce Feynman amplitudes. Information about the physical model, such as the Feynman rules, is provided in a so-called model file.

Restrictions:
Currently diagrams up to three loops can be generated. Model files other than the Standard Model and QCD (and soon also the Minimal Supersymmetric Standard Model) are not contained in FeynArts and must be set up by the user.

Unusual features:
FeynArts can produce high-quality images of the Feynman diagrams e.g. in PostScript or LaTeX format for inclusion in publications.

Running time:
About a minute to generate all amplitudes for a one-loop, 2 -> 2 process in the electroweak Standard Model.
