Xfey, a Feynman diagram editor Original Research Article

A graphical program, suitable for Feynman diagram drawings, is presented. It is mouse driven and easy to use. It is intended for those physicists who think they spend too much time drawing Feynman diagrams and want a tool to speed up the process. Its main feature is that it is a “what you see is what you get” (WYSIWYG) application, that is, its Postscript output mirrors exactly what has been drawn on the screen. The program has a lot of room for improvement but it is fully functional.
