TikZ-Feynman: Feynman diagrams with TikZ

TikZ-Feynman is a LaTeX package allowing Feynman diagrams to be easily generated within LaTeX with minimal user instructions and without the need of external programs. It builds upon the TikZ package and leverages the graph placement algorithms from TikZ in order to automate the placement of many vertices. TikZ-Feynman still allows fine-tuned placement of vertices so that even complex diagrams can be generated with ease.Program summaryProgram title: TikZ-FeynmanCatalogue identifier: AFBF_v1_0Program summary URL:http://cpc.cs.qub.ac.uk/summaries/AFBF_v1_0.htmlProgram obtainable from: CPC Program Library, Queen's University, Belfast, N.

This can be combined with some positioning to produce complicated diagrams with relative ease.Running time:Depends on the size
