The Electric Charge Assignment in $SU(4)_{L}\otimes U(1)_{Y}$ Gauge Models

Abstract

In this brief report, apart from the usual approach, we discriminate among models in the class of \textbf{$SU(4)_{L}\otimes U(1)_{Y}$} electro-weak gauge models by just setting the versors in the method of the exactly solving gauge models with high symmetries. We prove that the method itself naturally predicts the correct assingment of the electric charge spectrum along with the relation between the gauge couplings of the groups involved therein for each particular model in this class.
