TikZ-Feynman is made available through the Comprehensive TeX Archive Network (CTAN) and comes with some thorough documentation containing a tutorial and many examples. Feynman diagrams represent interactions between matter particles (fermions, including quarks and leptons) and their corresponding force carriers (bosons). They consist of points, called vertices, which represent the interactions and lines attached to the vertices which represent the fermions and bosons involved in the interaction. 2013-03-31 · Feynman diagrams help show the decay of sub-atomic particles.
