Possible New Resonance from WLWL-h h Interchannel Coupling
Abstract
We propose and theoretically study a possible new resonance caused by strong coupling between the Higgs-Higgs and the WLWL (ZLZL) 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.
