Feynman Diagrams of the QED Vacuum Polarization

Authors: Richard J. Mathar

The Feynman diagrams of Quantum Electrodynamics are assembled from vertices where three edges meet: an incoming fermion, an outgoing fermion and an interaction line. If all vertices are of degree 3, the graphs are 3-regular (cubic), defining the vacuum polarization diagrams. Cutting an edge -- a fermion line or an interaction line -- generates fairly cubic graphs where two vertices have degree 1. These emerge in the perturbation theory for the Green's function (self energy) and for the effective interaction (polarization). The manuscript plots these graphs for up to 8 internal vertices.
