Strongly interacting vector bosons at TeV e+ e- linear colliders

In the absence of light Higgs bosons, the $W$ and $Z$ bosons become strongly interacting particles at energies of about 1 TeV. If the longitudinal $W,Z$ components are generated by Goldstone modes associated with spontaneous symmetry breaking in a new strong interaction theory, the quasi-elastic $W,Z$ scattering amplitudes can be predicted as a systematic chiral expansion in the energy. We study the potential of TeV ${e}^{+}{e}^{\ensuremath{-}}$ and ${e}^{\ensuremath{-}}{e}^{\ensuremath{-}}$ linear colliders in investigating these scattering processes. We estimate the accuracy with which the coefficients of the chiral expansion can be measured in a multi-parameter analysis. The measurements will provide us with a quantitative test of the dynamics underlying the $W,Z$ interactions.
