Summary
The existence of four independent neutrino states is related to the two conservation laws for leptons. The first is the usual law of lepton conservation, associated with gauge transformations of the fields, while the second is derived from the γ5 gauge transformations of the neutrino field. The experimental basis of these laws is discussed.
Riassunto
Si ricollega l‘esistenza di quattro stati neutrinici indipendenti alle due leggi di conservazione per i leptoni. La prima è la solita legge di conservazione dei leptoni, associata alle trasformazioni di gauge del campo, mentre la seconda è dedotta dalla trasformazione di gauge γ5 del campo neutrinico. Si discute la base sperimentale di queste leggi.
