HERA Physics Feynman Diagram Gallery

by Gerhard Brandt

Some Feynman diagrams I created in the course of my work at H1.
Images are linked to eps files. Please feel free to use them (If you like sent me an email).
In case you notice a bug, don't hesitate to contact me.
Also, if you need a nice diagram in the same style that is still missing, feel free to ask. I will be happy to draw it when time permits.
