By T. Hahn. 2000

1,829 citations recorded by the source corpus.

This paper describes the Mathematica package FeynArts used for the generation and visualization of Feynman diagrams and amplitudes. The main features of version 3 are: generation of diagrams in three levels, user-definable model files, support for supersymmetric models, and publication-quality Feynman diagrams in PostScript or LaTeX.

Electroweak contribution to the top quark forward-backward asymmetry at the Tevatron (2011, methodology): “The numerical analysis is based on the analytical evaluation of the required symmetric and antisymmetric parts of the parton cross sections and semi-numerical phase-space integration for the radiation processes with phase-space slicing, with support of FeynArts [21] and FormCalc [22].”
From superpotential to model files for FeynArts and CalcHep/CompHep (2009, methodology): “After the automatized calculations are finished, you can just play with the model by checking distinct vertices, look at the different mass matrices, give numerical values to the parameters and calculate the mass spectrum, or you can generate model files for FeynArts and CompHep/CalcHep for further ”
Next-to-leading-order electroweak corrections to the production of four charged leptons at the LHC (2016, methodology): “The one-loop matrix elements of the mixed-flavour case have been checked against a calculation based on diagrammatic methods like those developed for four-fermion production in electron–positron collisions [46, 61], starting from a generation of amplitudes with FeynArts [58, 59] and further algebrai”

Feynman rules for the Standard Model Effective Field Theory in Rξ-gauges (2017, background): “The evaluated Feynman rules can be exported in several commonly used formats (Latex, UFO [35], FeynArts [36] and others), such that they can be directly fed to other symbolic or numerical packages for high energy physics calculations.”

Two-Loop Electroweak Corrections for the K -> pi nu anti-nu Decays (2010, methodology): “fter setting external momenta and light masses to zero. The resulting loop integrals are computed using standard methods [16,17].
