DescriptionVacuum polarization.svg |
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. |
