The possibility that both vector and axial-vector bound states could originate from a strong interacting sector of the electroweak theory is considered. A simple Lagrangian parametrization is presented where the bound states are described as gauge vector bosons of a local, nonlinearly realized, SU(2) circle times SU(2) symmetry. At present the model is mostly constrained from data on W and Z masses and on neutrino-nucleon deep inelastic scattering. High energy e/sup +/e/sup -/ tests are suggested where visible deviations from the standard model predictions could take place. These deviations exhibit a certain pattern which allows to distinguish the model from other theoretical frameworks. The authors find that precise measurements of W and Z masses and asymmetries in e/sup +/e/sup -/ collisions could put strong restrictions on the parameters of the model if no appreciable deviations are found from the standard model, except for a case with the vector and axial-vector bosons degenerate in mass and coupling. General differences with respect to technicolor are pointed out.
