SUSY particles Feynman diagrams
I created a package called TikZ-Feynman which is available from CTAN, and in today's update, I have added support for SUSY particles by allowing edge styles to be stacked.
Here's the code for the above diagram
\documentclass[tikz]{standalone}
\usepackage[compat=1.1.0]{tikz-feynman}
\begin{document}
\feynmandiagram [large, horizontal=a to b] {
i1 [particle=\(\langle H_{u} \rangle\)]
-- [scalar, with reversed arrow=0.3, insertion=0.7, edge label=\(H_{2}\)] a
-- [anti fermion, boson]
i2 [particle=\(\lambda\)],
a -- [anti majorana, insertion=0.5, edge label={\(\tilde H_{2}\quad\tilde H_{1}\)}] b,
f1 [particle=\(\tilde f\)]
-- [charged scalar] b
-- [anti fermion]
f2 [particle=\(f'\)],
};
\end{document}
and the corresponding output:
Note that the lines are fairly thick here because of the large
style being used.
