Generating function for web diagrams

Understand

We present the description of the exponentiated diagrams in terms of generating function within the universal diagrammatic technique.

• In particular, we show the exponentiation of the gauge theory amplitudes involving products of an arbitrary number of Wilson lines of arbitrary shapes, which generalizes the concept of web diagrams.
• The presented method gives a new viewpoint on the web diagrams and proves the non-Abelian exponentiation theorem.
