Strongly interacting W bosons at e-e- colliders

If no Higgs boson exists, scattering amplitudes of massive vector bosons become strong at TeV energies. Below the threshold where new resonances appear, they are described by an effective chiral Lagrangian, which introduces a small number of new universal parameters at each order of a low-energy expansion. These parameters can be measured in (quasi-)elastic scattering processes of massive vector bosons in e(-)e(+/-) collisions. Analyzing processes 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.
