\begin_layout Standard
To be able to use
\noun on
Feynman
\noun default
diagrams, the LaTeX-package
\series bold
feyn
\series default
must be installed.
A Feynman diagram is created by inserting the command
\series bold
\backslash
Diagram
\series default
in a formula.
Then you are able to add new matrix columns and rows like a normal matrices.
\end_layout
\begin_layout Standard
As matrix entry, one can enter commands that act as
\begin_inset Quotes eld
\end_inset
particles
\begin_inset Quotes erd
\end_inset
or
\begin_inset Quotes eld
\end_inset
propagators

Note:

If you have an index list in your document and use one of the AMS theorem
modules, you have to add the option
\series bold
noglobalbang
\series default
to the document class options in the document settings.
This enables the usage of the '!' character in index entries (necessary
for subentries) but might cause troubles with the AMS align and align*
environments (which are described in section
