Weak interaction symmetry and generation structure in the quasi-Nambu-Goldstone fermion picture of quarks and leptons

We discuss composite models where massless quarks and leptons arise as superpartners of composite Goldstone bosons, resulting from the spontaneous breakdown of global symmetry, in a supersymmetric theory in which the preons are confined by nonabelian hypercolor dynamics. We present different schemes for including the generations. Finally, we note some problems with this approach. (orig.)
