## Feynman Diagrams using Adobe Illustrator

In a previous post, I briefly outlined the installation of FeynArts, an open source Mathematica package for creating Feynman diagrams. There are also other tools such as the open source JaxoDraw program, and the axodraw $\LaTeX$ file, which Jaxodraw actually uses to export diagrams into $\LaTeX$ lineart. I personally endorse the use of open source programs such as FeynArts and Jaxodraw, but for those of you who already have access to Adobe Illustrator, you might find these videos quite useful.
