  We present some results on the usefulness of upgraded Tevatron, LHC proton proton collider and linear e+e- colliders in the TeV range to test the idea of a strongly interacting sector as responsible for the electroweak symmetry breaking. The calculations are performed within an effective lagrangian description, called the BESS model, which provides for a rather general frame based on the standing point of custodial symmetry and gauge invariance, without specifying any dynamical scheme.
