Abstract: (Elsevier)
We have written Feyn Arts , a program which generates all tree and one-loop graphs for processes with given external particles in a given renormalizable field theory without mixing propagators. Successively all topologies are created, particles and Feynman rules are inserted and the graphs are drawn. The obtained amplitudes are suited for evaluation by the program Feyn Calc. We have entered the Feynman rules for the electroweak standard model and have applied the program to different processes within this model.- Feynman graph: higher-order
- field theory: renormalizable
- S-matrix
- electroweak interaction
- programming
