Neutrinos and Electromagnetic Gauge Invariance

Abstract

It is discussed a recently proposed connection among U(1)${}_{\mathrm{em}}$ electromagnetic gauge invariance and the nature of the neutrino mass terms in the framework of $\mbox {SU(3)}_C\otimes G_W \otimes {\mbox U(1)}_N$, $G_W$ = SU(3)${}_L$, extensions of the Standard Model. The impossibility of that connection, also in the extended case $G_W$ = SU(4)${}_L$, is demonstrated.
