Dynamical resonances in strongly coupled Higgs models

Abstract
The scattering of Goldstone and longitudinal gauge bosons in weak-interaction theories with a strongly coupled Higgs sector is studied. By combining low-energy theorems with analyticity, unitarity, and crossing symmetry, it is argued that, quite generally in such theories, one would expect a prominent resonance in the I=J=1 channel (where I=weak isospin) analogous to the ρ resonance in π-π scattering. Implications for p¯p collider events are explored.
