Abstract

A horizontal U(1) gauge symmetry is proposed to distinguish two fermionic generations. By extending the notion of generation structure to the Higgs system, and using anomaly-free conditions with the requirements of lepton-number conservation and proper Cabibbo structure, we determine Y associated with U(1), uniquely. The model can easily be generalized to account for 2N (N=1,2,) generations.
