A model of the composite structure of quarks and leptons with SU(4) gauge symmetry
arXiv:hep-ph/9801382
Abstract
A model in which quarks and leptons consist of three "more elementary" particles of spin 1/2 is proposed. A gauge field theory with SU(4) symmetry that corresponds to this model predicts the existence of two new bosons.
