Summary
A tentative model, a modification of Konopinski-Mahmoud’s model concerning the leptons is developed for the classification of the processes where leptons take part. By means of this model, we obtain a good selection rule, and also the redundant neutral particle has not been introduced which always appears in the model based on the charge independence hypothesis extended to leptons. We have referred to the relation between the N-G model and our scheme and shortly discussed the interaction structure with this scheme. And though we obtain a good selection rule for lepton processes, we conclude that for a classification of leptons, their interaction structure is always to be taken into account.
Riassunto
Si sviluppa un modello di prova, modificazione del modello di Konopinski-Mahmoud Tiguardante i leptoni, per la classificazione dei processi cui partecipano leptoni. Per mezzo di questo modello si ottiene una buona regola di selezione, senza dover introdurre la particella neutra sovrabbondante che sempre appare nei modelli basati sulla ipotesi dell’indipendenza della carica applicata ai leptoni. Si fa in breve riferimento alla relazione tra il modello N-G e il nostro schema e si discute al lume di tale schema la struttura dell’interazione. E per quanto si ottenga una buona regola di selezione per processi leptonici, si conclude che per una classiflcazione dei leptoni si deve sempre tener conto della loro struttura di interazione.
