▪
The is a topology graph as produced by or — its vertices are interaction points and external legs, its tagged edges are propagators.
graph
▪
Each vertex becomes a subdiagram (a point for interaction vertices, an invisible node for external legs) and each propagator becomes a wire, rendered with the line style conventional for its FeynArts propagator type (wiggly for gauge bosons, dashed for scalars and ghosts, straight for fermions) via .
▪
When the edges carry field insertions (from via ), the wires are labelled with the LaTeX-typeset field names.
