  • Abstract The possibility of additional quarks and leptons beyond the three generations already established is discussed. The make-up of this Report is (1)  Introduction : the motivations for believing that the present litany of elementary fermions is not complete; (2)  quantum numbers : possible assignments for additional fermions; (3)  masses and mixing angles : mass limits from precision electroweak data, vacuum stability and perturbative gauge unification; empirical constraints on mixing… CONTINUE READING
