I would like to put an overall title for a FeynMP diagram, as it is going to be put in a figure side by side with many other Feynman diagrams. I would like it to look something like this:
The option to put it either top or bottom would be also welcome. The source without the title is as follows:
\documentclass{article}
\usepackage{feynmp}
\DeclareGraphicsRule{*}{mps}{*}{}
\begin{document}
\thispagestyle{empty}
\unitlength = 1mm
%lb - left bottom
%rt - right top
\begin{fmffile}{gluon}
\begin{fmfgraph*}(30,30)
\fmfleft{lb,lt}
\fmflabel{Left bottom}{lb}
\fmflabel{Right bottom}{rb}
\fmfright{rb,rt}
\fmflabel{Right top}{rt}
\fmflabel{Left top}{lt}
\fmf{fermion}{lb,v1}
\fmf{fermion}{v1,rt}
\fmf{dashes_arrow}{rb,v1}
\fmf{fermion}{v1,lt}
\fmfdot{v1}
\end{fmfgraph*}
\end{fmffile}
\write18{mpost gluon}
\end{document}
Any information will be appreciated!
\write18{mpost gluon}
