FeynFig is a program to generate feynman diagrams in xfig format. It can be used in two ways: one can write an input file describing the feynman diagram to be drawn. FeynFig will then convert this to an xfig file.
A second, often more convenient approach, is to use FeynFig to generate a template of gluons, quarks, photons, ... These can then be merged into your xfig file, copied, moved, rotated, chopped etc., in order to produce the final diagram that is desired. Some sample templates are included with the distribution.
FeynFig is based on FeynMongo by Paolo Nason and Manfred Lindner. It was adapted for xfig and enhanced by Gavin Salam with further additions and man page by Thomas Pollehn.
Download current version: feynfig-1.2b.tar.gz
You may also want to download an XFig library file, Feynman_Diagrams.tgz, containing various basic Feynman diagram elements. This should be uncompressed in the xfig library directory, for example (on RedHat Fedora):
cd /usr/X11R6/lib/X11/xfig/Libraries/ gunzip -c Feynman_Diagrams.tgz | tar xvf -The feynman diagram elements will be available from the library tool on your next invocation of xfig.
