PSEUDO GOLDSTONES AT FUTURE COLLIDERS FROM THE EXTENDED BESS MODEL

We consider the production of the lightest pseudo-Goldstone bosons at future colliders through the vector resonances predicted by the extend ed BESS model, which consists of an effective lagrangian parametrizati on with dynamical symmetry breaking, describing scalar, vector and axi al-vector bound states in a rather general framework. We find that the detection of pseudo-Goldstone pairs at LHC requires a careful evaluat ion of backgrounds. For e(+)e(-) collisions in the TeV range the backg rounds can be easily reduced and the detection of pseudo-Goldstone pai rs is generally easier.
