On the universal fermi-type interaction (II)

  • Published:
Il Nuovo Cimento (1943-1954)

Summary

We search for a universal interaction among all known fermions based on invariance under the extended Lorentz group which will exclude all processes not occurring in nature. Two mutually exclusive interactions appear ultimately to be the only ones consistent with certain plausible criteria of simplicity. The two possible interactions are proved to yield identical numerical answers in the case of free fermions; one at least of them is in excellent agreement with all the experimental evidence available thus far.

Riassunto

Si ricerca un'interazione universale tra tutti i noti fermioni, che escluda tutti i processi non occorrenti in natura a mezzo della sua invarianza rispetto a trasformazioni del gruppo di Lorentz ampliato. Si pervienes, usando plausibili criteri di semplicità, a soltanto due interazioni, mutuamente esclusive, una almeno delle quali risulta in eccellente accordo con tutti i dati sperimentali noti fino ad oggi. Si dimostra inoltre che le due possibili interazioni danno identici risultati numerici nel caso di processi involventi particelle libere.
