Strongly interacting W bosons at e(-)e(-) colliders

If no Higgs boson exists, scattering amplitudes of massive vector bosons be come strong at TeV energies. Below the threshold where new resonances appea r, they are described by an effective chiral Lagrangian, which introduces a small number of new universal parameters at each order of a low-energy exp ansion. These parameters can be measured in (quasi-)elastic scattering proc esses of massive vector bosons in e(-)e(+/-) collisions. Analyzing processe s such as e(-)e(-) --> nu(e)nu(e)W(-)W(-) a sensitivity of the order 10(-2) can be reached at a high-luminosity 1 TeV linear collider.
