feynMF - Drawing Feynman Diagram

feynMFis a tool made by Thorsten Ohl to draw Feynman diagrams in LaTeX. There are three parts of official tutorials on feynMF: Part 1, Part 2 and Part 3. I have also written several examples. A more comprehensive and pedagogical manual comes with the package that you will download next.

How to install feynMF

1. Download the entire directory of feynmf stuffs from CTAN site. Not all the sites have feynmf, but one of the sites which has fynmf is ftp.dante.de.
2. Expand the downloaded feynmf.tar.gz if necessary.
3. From Terminal, go into the feynmf directory, and type
   % make
4. Next, copy 4 files into specific directories. If you are the only person who uses feynmf, you can copy them under your home directory.
   

   					% mkdir -p ~/texmf/tex/feynmf
   					% mkdir -p ~/texmf/metafont/feynmf
   					% mkdir -p ~/texmf/metapost/feynmf
   					% cp feynmf.sty ~/texmf/tex/feynmf
   					% cp feynmp.sty ~/texmf/tex/feynmf
   					% cp feynmf.mf ~/texmf/metafont/feynmf
   					% cp feynmp.mp ~/texmf/metapost/feynmf
   					% mktexlsr
   					

How to use feynMF

• Try running template.tex, by following the 3 commands shown at the beginning of the file. This should create template.dvi which has a simple diagram.
• mf command should be run from Terminal, but latex can be run from TeXShop by hitting "Typeset" button as usual.
• Read manual.ps in the downloaded package for instructions.
• For each diagram, you should give a file name (without extension) as an argument for fmffile, such as:

  						\begin{fmffile}{tree1}
  						....
  						\end{fmffile}
  						
  						\begin{fmffile}{penguin1}
  						....
  						\end{fmffile}
  					

• Typeset once to make mf files. For each diagram, you will get a mf file with extension, '.mf', such as tree1.mf and penguin1.mf .
• For diagrams which contain lables on particles or vertices, run mf such as:

  						% mf '\mode:=localfont;' input tree1
  						% mf '\mode:=localfont;' input penguin1
  					

  This makes several files, such as: tree1.600gf, tree1.600pk, tree1.log, tree1.tfm, etc..
• For diagrams which do not contain labels on particles or vertices, you do not have to run mf command.
• Typeset again to load the created metafont showing diagrams.
• If you edit a diagram, make sure that you at least delete the corresponding ".600pk" file before running mf. Otherwise, the diagram will not be updated
• Do not put space characters between vertecies. You should write like

  						\fmfleft{v1,v2,v3}
  					

  , and not like

  						\fmfleft{v1, v2, v3}
  					

  . Otherwise, you will get get a message like:

  						feynmf: warning: dangling vertex `v1' colliding with `v2'.
  						feynmf: Have you seen the warning messages above?
  					

  when you run mf.
