Properties of a composite Higgs particle in a dynamically broken formulation of the standard model

We suggest that dynamical breakdown of electroweak symmetry in an SU(3)×{}SU(2)×{}U(1) model of a single fermion family without fundamental scalars can reproduce the entire scalar sector of the standard model through fermion bound states and loop-induced couplings. The physical Higgs boson is essentially a tt{} bound state. The top-quark and Higgs-boson masses are approximately 300 and 400 GeV, respectively. The strengths of the induced couplings among the scalars do not indicate a strongly interacting scalar sector.
