%0 Journal Article %T How many SU(4)L X U(1)Y Gauge models ? %A Adrian Palcu %J Theory and Applications of Mathematics & Computer Science %D 2012 %I Aurel Vlaicu University Editing House %X We prove in this letter that the general method of solving gauge models with high symmetries proposed by Cot escu several years ago can predict precisely two distinct classes of SU(4)L X U(1)Y electroweak models. Their fermion representations with respect to this gauge group are exactly obtained in rach case. %K 3-4-1 gauge models %K electric charge assignment %U http://www.uav.ro/applications/se/journal/index.php/TAMCS/article/view/67/49
