Abstract We explore the usefulness of very energetic lineare + e − colliders in the TeV range in studying an alternative scheme of electroweak symmetry breaking based on a strong interacting sector. The calculations are performed within the BESS model which contains new vector resonances. If the massM V of the new boson multiplet lies not far from the maximum machine energy, or if it is lower, such a resonant contribution would be quite manifest. A result of our analysis is that also virtual effects are important. It appears that annihilation into a fermion pair in such machines, at the considered luminosities, would improve only marginally on existing limits if polarized beams are available and left-right asymmetries are measured. On the other hand, the process ofW-pair production bye + e − annihilation would allow for sensitive tests of the hypothesized strong sector, especially if theW polarizations are reconstructed from their decay distributions, and the more so the higher the energy of the machine. Ane + e − collider with c.m. energy $$\sqrt s = 500$$ GeV could improve the limits on the model for the range 500〈M V (GeV)〈1000 whenW polarization is not reconstructed. IfW polarizations are reconstructed, then the bounds improve for the entire expected range ofM V . These bounds become more stringent for larger energy of the collider. We have also studied the detectability of the new resonances through the fusion subprocesses, but this channel does not seem to be interesting even for a collider with a c.m. energy $$\sqrt s = 2$$ TeV.
