Peratization of some higher-order diagrams

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The peratizational approach has been applied to the Bethe-Salpeter equation including some higher-order irreducible diagrams. The most detailed and exact results are given for irreducible diagrams with the exchange of one boson line and of two crossed boson lines.

Riassunto

Si applica l’approssimazione della peratizzazione alla equazione di Bethe-Salpeter comprendendo alcuni diagrammi irriducibili di ordine piu elevato. Si danno i risultati piu dettagliati ed esatti per i diagrammi irriducibili con lo scambio di una linea bosonica e di due linee bosoniche incrociate.
