Welcome to the Feynman Diagram Library (FDL)


The Feynman Diagram Library is an open tool to create, share and search for Feynman diagrams. The diagrams base on the the FeynMF LaTeX package by Thorsten Ohl.
You can search for existing diagrams under Search or List. If you do not find the diagram you like, download (Login/Registration required) the package and create the wanted diagram on your own (examples are available in the package). We encourage you to upload (Login/Registration required) the created diagrams and thus to provide them to other people.
