Propagating Higgs bound states in SUSY

The possibilities for an underlying theory behind an effective supersymmetric Nambu-Jona-Lasinio like model of electroweak symmetry breaking with propagating Higgs bound states (e.g. supersymmetric topcondensation) are investigated. The concept of a renormalizable underlying theory turns out not to be appropriate. We argue that the new theory should come from the Planck scale and be connected to supergravity. Such a model can be constructed but necessarily implies a nonlinear definition of the full Lagrangian.
