Possible Extensions of the Unified Model for Fundamental Particles

(Received June 3, 1976)
Starting from usual quartet model (4-quarks and 4-leptons), possible extensions of the model are discussed. In order that two fundamental principles are assumed; one is “modified B-L symmetry” and the other is “ε-symmetry”, models are required to be “closed” for these principles. Sixteen possible models and their weak interactions, including extra leptons, extra quarks and right-handed currents, are presented.
