Pair effects in the lee model

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The Lee model of an exactly soluble, renormalizable field theory is extended by allowing the meson to make nucleon pairs, introducing a new nucleon field for the purpose. The theory is still exactly soluble, with the following results; logarithmic divergences remain in the theory after renormalization, and the ghost state is shifted from the V-particle spectrum to the meson spectrum.

Riassunto

Si estende il modello di Lee di una teoria di campo rinormalizzabile esattamente risolvibile consentendo al mesone di creare coppie di nucleoni introducendo allo scopo un nuovo campo nucleonico. La teoria è ancora esattamente risolvibile, coi seguenti risultati: dopo rinormalizzazione permangono nella teoria divergenze logaritmiche e lo stato fantasma è spostato dallo spettro delle particelle V allo spettro dei mesoni.
