We examine ways to obtain experimental information on WW scattering (W = W ±, Z0) at future hadron or e+e− colliders. Perturbative standard model predictions for the production of W pairs, including pairs arising from WW → WW (which have not previously been studied) are presented. Methods of obtaining information from W polarizations as well as cross sections are considered. We find that with appropriate detectors it should be feasible to measure W polarizations. By determining the fraction of W's which are longitudinally polarized it is possible to extend the range of Higgs' masses which can be studied perhaps even to 2 TeV at future colliders, even when no signal can be seen in the cross section. The correlation of W decay planes turns out to be very small at any energy above threshold due to a previously unnoticed consequence of the standard model. Any non-zero correlation would be a signal of new physics. Some discussion is given of the requirements on detectors in order to have a reasonable chance to detect WW interactions. We also comment briefly on backgrounds which could mimic W pair production.
