Summary
It is pointed out in connection with a universal Fermi interaction that conservation of axial vector current does not ensure non-renormalization of the axial vector coupling constant for strongly interacting particles. A discussion is given of possible renormalizing processes and their effects.
Riassunto
Si fa rilevare a proposito della interazione universale di Fermi che la conservazione della corrente di vettore assiale non assicura la non rinormalizzazione della costante d’accoppiamento del vettore assiale per particelle fortemente interagenti. Segue una discussione sui possibili processi di rinormalizzazione e dei loro effetti.
