CollinearU 6 symmetry and pole models for nonleptonic hyperon decays

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

Nonleptonic hyperon decays are considered using the spurion scheme of brokenU 6,6 symmetry directly and in connection with a pole model. In the pole modelU 6 symmetry-breaking effects are taken into consideration. The model then gives the Lee-Sugawara relation without additional restrictions.

Riassunto

Si studiano i decadimenti iperonici non leptonici facendo uso dello schema spurionico della simmetriaU 6,6 infranta, direttamente e in connessione con un modello a poli. Nel modello a poli si prendono in considerazione gli effetti dell'infrazione della simmetriaU 6. Il modello dà allora la relazione di Lee-Sugawara senza ulteriori restrizioni.
