LaTeX question about Feynman Diagrams

[ChrisVer]

Has anyone of you tried to work with creating Feynman Graphs in LaTeX?

I tried using the feynmf package, as explained here:
https://www.sharelatex.com/learn/Feynman_diagrams
and used the same introductory script:
\begin{fmffile*}{diagram}
\begin{fmfgraph}(40,25)
\fmfleft{i1,i2}
\fmfright{o1,o2}
\fmf{fermion}{i1,v1,o1}
\fmf{fermion}{i2,v2,o2}
\fmf{photon}{v1,v2}
\end{fmfgraph}
\end{fmffile*}

Trying to run it like this doesn't work, and during compiling I get the message that (\begin{fmffile*}{diagram}) is wrong... After removing the *, the compiling works, but I get a very weird graph which:
1. Is very small
2. I am not able to interfere with... (like changing the lines-vertices)

Has anyone ever had that problem? any way to solve it?

I have no experience with feynmf, I usually use axodraw and it works reasonably.

 

[ChrisVer]

Do you understand what the procedure:
"latex-dvips-ps2pdf route"
means? Because TeX won't make axodraw work with pdflatex...

I vaguely remember that I had to run metafont (?) whenever I changed something in a fmffile-environment before running pdflatex.

Hi there,

As a fellow scientist, I have also encountered difficulties with creating Feynman diagrams in LaTeX. The feynmf package can be tricky to use, and it's important to make sure that all the necessary files are in the same directory as your LaTeX document. In addition, the * in \begin{fmffile*} is used for externalizing the diagrams, so if you don't need that feature, you can remove the *.

If you're still having issues with the size and appearance of your graph, I suggest looking into other packages such as TikZ-Feynman or feynman, which may be easier to use and provide more control over the diagram's appearance. You can also try adjusting the scale of your graph by using the \fmfset{...} command before \begin{fmfgraph}.

I hope this helps, and I wish you success in creating your Feynman diagrams in LaTeX!
