SU(3)_{L} \times U(1)_{X} Models of Electroweak Unification with Natural Conservation Laws for Neutral Currents

Authors: Murat ÖZER

Abstract: SU(3)_{L} \times U(1)_{X} models of electroweak interactions with natural conservation laws for neutral currents are searched for. A class of models in which left-handed fermions transform as triplets of SU(3)_{L} are found to be satisfactory. SU(3)_{L} \times U(1)_{X} models are further classified as {\it natural, semi-natural,} and {\it unnatural} in regard to the natural conservation laws.
