text: The interaction of zigs and zags is a W-shape on a Feynman diagram, and according to Feynman’s rules (very nicely explained with clear examples in the 2008 book Quantum Field Theory Demystified) the amplitude for an interaction is simply the product of the various coupling constants and propagators involved, integrated in such a way as to conserve momentum for the interaction.
