R-invariances of strong and weak interactions

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

Three alternative formulations of invariance under hypercharge (R) conjugation are considered. Some consequences of the three forms ofR-invariance are presented for weak interactions (both leptonic and nonleptonic) as well as for strong and electromagnetic interactions. Existing experimental data disfavor the standard form but are consistent with the other two forms ofR-invariance. Further experimental tests are needed to confirm the value of the new symmetry principle.

Riassunto

Si considerano tre formulazioni alternative dell‘invarianza rispetto alla coniugazione dell‘ipercarica (R). Si presentano alcune conseguenze delle tre forme di invarianza rispetto aR per le interazioni deboli (sia leptoniche che non leptoniche) e per le interazioni forti ed elettromagnetiche. I dati sperimentali esistenti sono a sfavore della forma standard ed invece sono compatibili con le altre due forme di invarianza rispetto aR. Necessitano ulteriori verifiche sperimentali per confermare la validità del nuovo principio di simmetria.
