Description

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 the known left handed neutrinos and new right-handed ones that obtain their masses through interaction with a new scalar field whose vacuum is broken spontaneously. We discuss some of the possible consequences of the model and ways of constraining the parameter space.
