Feyn: a Metafont for Feynman diagrams ------------------------------------- Version 0.3.3. This package is intended to produce relatively simple Feynman diagrams, for example within equations. This package differs from Thorsten Ohl's feynmf/feynmp package. FeynMP works by creating Metafont or MetaPost figures using a preprocessor. It's more general than this package, but is at its best when creating relatively large diagrams, for figures. In contrast, the present system consists of a carefully-designed font with which you can easily write simple diagrams, within equations or within text, in a size matching the surrounding text size. The propagators and vertices which are implemented are those which seem to appear most often in non-figure displays (the practical definition of `appear most often' is `which I wanted' and `which people asked me for'). I have no current plans to extend the package further, but I'm willing add other features if you can make a case for them, and they fit within the package's remit of 'diagrams for use in equations'. The package is on CTAN, and is included in TeXLive but not, as far as I'm aware, teTeX. The arXiv started using TeXLive 2008 in summer 2008 (I understand), so it should be available there from that date. There is further documentation, plus numerous examples, in the package documentation (feyn.pdf). See the package's home page on the web: http://purl.org/nxg/dist/feyn Installation ------------ Extract the package file from the distribution file using `latex feyn.ins'. The resulting `feyn.sty' should be installed in the usual location for style files -- that is, something like `texmf.local/tex/latex/feyn.sty'. The Metafont source files `*.mf' should be installed in a directory with a location such as `texmf.local/fonts/source/feyn/' (on a system which has the command, `kpsepath mf' will indicate the possibilities here, but these typically include the current directory). That should be all you need to do as regards the installation of the fonts -- if your TeX setup is installed correctly, then the usual font-generation commands (such as `mktexpk' for example) should work as normal, and they should be invoked by default when you LaTeX the feyn.dtx file. You should be able to find generic instructions for installing LaTeX files at http://www.tex.ac.uk/cgi-bin/texfaq2html?label=installthings Licence ------- This software is copyright, 1991, 2001, 2002, 2005, 2008, Norman Gray.

feyn – A font for in-text Feynman diagrams
Feyn may be used to produce relatively simple Feynman diagrams within equations in a LaTeX document. While the feynmf package is good at drawing large diagrams for figures, the present package and its fonts allow diagrams within equations or text, at a matching size.
The fonts are distributed as METAFONT source, and macros for their use are also provided.
