Repetition of the quark-lepton states in a supersymmetric composite model with complementarity

In a supersymmetric composite model based on an SU(4)sub(sc)sup(loc) confining theory, complementarity is used to support the symmetry-breaking pattern and spectrum of massless particles in a confining phase. The model is found to accommodate two generations of quarks and leptons as quasi Nambu-Goldstone fermions and another two generations as chiral fermions. Masses of composite particles are examined and the quark-lepton generations are classified according the possible mass splittings. The suppression of dangerous flavor-changing interactions is considered also. (orig.)
