Electroweak Symmetry Breaking by Strong Supersymmetric Dynamics at the TeV Scale

Abstract

We construct models in which electroweak symmetry is spontaneously broken by supersymmetric strong dynamics at the TeV scale. The order parameter is a composite of scalars, and the longitudinal components of the W and Z are strongly-coupled bound states of scalars. The usual phenomenological problems of dynamical electroweak symmetry breaking are absent: the sign of the S parameter unconstrained in strongly interacting SUSY theories, and fermion masses are generated without flavor-changing neutral currents or large corrections to the rho parameter. The lightest neutral Higgs scalar can be heavier than M_Z without radiative corrections from standard-model fields. All the mass scales in the model can be naturally related in low-scale models of supersymmetry breaking. The mu problem can also be solved naturally, and the model can incorporate perturbative unification of standard-model gauge couplings with intermediate thresholds.
