Strong electroweak symmetry breaking at future super collider

One of the most important questions in particle physics which has to be answered today by future super collider is what the mechanism of electroweak symmetry breaking is. I a light Higgs is absent below 1 TeV, longitudinally polarized W's, i.e., WL should interact strongly with themselves at high energies, since the theory without a scalar gives a bad high energy behavior. This inevitably leads us to a new strong interactions. To investigate new physics, we use the techniques of strong interactions which had bloomed in 1960's with new modification. This new method can also be applied to hadron physics. (author)
