We consider an anomaly free extension of the standard model gauge group GSM by an abelian group to GSM U(1)Z. The condition of anomaly cancellation is known to fix the Z-charges of the particles, but two. We fix one remaining charge by allowing for all possible Yukawa interactions of the known left-handed neutrinos and new right-handed ones that obtain their masses through interaction with a new scalar field with spontaneously broken vacuum. We discuss some of the possible consequences of the model.
- Extension of the standard model of particle interactions
- Gauge symmetry
