| Description |
English: One-loop vacuum polarization diagram. This is the one loop contribution to the photon propagator Π due to vacuum polarization in quantum electrodynamics. It contributes to a wave function renormalization for the photon, leading to a charge screening. It has a logarithmic divergence. Similar one-loop diagrams can be considered for other gauge bosons, such as W, Z and the gluons.
Français : Diagramme à une boucle de polarisation du vide, ou d'écrantage des charges en QED. Il contribue à la renormalisation de la fonction d'onde du photon. Il possède une divergence ultraviolette logarithmique.
