Probing strongly interacting electroweak dynamics through W+W-/ZZ ratios at future e(+)e(-) colliders

We point out that the ratio of W+W- --> W+W- and W+W- --> ZZ cross sections is a sensitive probe of the dynamics of electroweak symmetry breaking, in the c.m. energy region root S-WW greater than or similar to 1 TeV where vector boson scattering may well become strong. We suggest ways in which this ratio can be extracted at a 1.5 TeV e(+)e(-) linear collider, using W-+/-,Z. --> jj hadronic decays and relying on dijet mass resolution to provide statistical discrimination between W-+/- and Z. WW fusion processes studied here are unique for exploring scalar resonances of mass of about 1 TeV and are complementary to studies via the direct channel e(+)e(-) --> W+W- for the vector and nonresonant cases. With an integrated luminosity of 200 fb(-1), the signals obtained are statistically significant. A comparison with a study of the e(-)e(-) --> nu nu W-W- process is made. Enhancements of the signal rate from using a polarized electron beam, or at a 2 TeV e(+)e(-) linear collider and possible higher energy mu(+)mu(-) colliders, are also presented.
