Abstract
Quarks and leptons together with other exotic fermions are regarded as quasi N ambu·Goldstone fermions and chiral fermions generated by supersymmetric quantum chromodynamics (SQCD) with Nco,oc( =N)<Nnavoc( =M). A mass protection symmetry, H, contains a chiral SU(M N) [or SU(M N + 1)] symmetry as well as a chiral U(l) symmetry supported algebraically by complementarity and dynamically by effective superpotential. The successive SUSY-breaking is constrained by the remnant of the QCD dynamics, i.e., the complete breakdown of chiral symmetries in H. The large mass splitting between /=1/2 and /=0 is shown to arise and masses for light composite fermions are specified by the SUSY-breaking scale Mss and the confinement scale il8C: Mss(Mss/il 8C )(M-N)/2K for Mss<t::il8C, where 2K~M N is imposed by the consistency with the anomalymatching.
