Abstract

We propose and theoretically study a possible new resonance caused by strong coupling between the Higgs-Higgs and the W_{L}W_{L} (Z_{L}Z_{L}) scattering channels, without regard to the intensity of the elastic interaction in either channel at low energy (that could be weak as in the standard model). We expose this channel-coupling resonance from unitarity and dispersion relations encoded in the inverse amplitude method, applied to the electroweak chiral Lagrangian with a scalar Higgs boson.
