Abstract
We consider the effective lagrangian for electroweak interactions in the limit of a strong interacting Higgs sector ( m H → ∞). We assume that the appearing SU(2) v hidden local symmetry is realized through a new dynamical vector boson resonance V. We derive the physical admixtures and masses of W, Z and V bosons and calculate the couplings of the physical bosons to fermions. No physical Higgs remains in the spectrum. We find that the standard low energy phenomenology of weak interactions, as well as the W-, Z-masses and properties, may be rather closely reproduced in our effective theory, even for low values of the mass of the new vector resonance, within presently accessible energies.
