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

Abstract

In a supersymmetric composite model based on an SU(4) loc sc 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 accomodate 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.
