ELECTRIC CHARGE QUANTIZATION IN SU(3)C ⊗ SU(3)L ⊗ U(1)X MODELS

Abstract

Basing on the general photon eigenstate and the anomaly cancellation, we have naturally explained the electric charge quantization in two models based on the SU (3)C ⊗ SU (3)L ⊗ U (1)X gauge group, namely in the minimal model and in the model with right-handed neutrinos. In addition, we have shown that the electric charges of the proton and of the electron are opposite; and the same happens with the neutron and the neutrino. We argue that the electric charge quantization in these models is closely related with the generation number problem. In fact, both problems are properly solved as the direct consequences of the fermion content under the anomaly free conditions.
