Origin of the SU(5) symmetry of quarks and leptons
Chkareuli Dzh. L.
Preons in a model with a unitary SU(3) metacolor form quarks and leptons in the ground state which show the standard SU(5) multiplets of symmetry 5 + 10. The complete local symmetry of the quarks and leptons is SU(6)H ® SU(6)V (a horizontal-vertical symmetry) and contains six SU(5) generations.
