- | The file contains a handy macro that allows you to compile Feynman graphs in LaTeX documents, without the need for extra scripts ([[https://tex.stackexchange.com/questions/20241/how-to-use-kile-with-feynmf-or-feynmp|source]]). Simply include the macro in the preamble. (Tested only in TeXShop on a Mac.) For Mac users however, [[http://osksn2.hep.sci.osaka-u.ac.jp/~taku/osx/feynmp_latexit.html|feynmp in LaTeXiT]] is a better option to quickly build of Feynman diagrams as standalone images. | + | <code latex feynman_macro.tex> |
