The Case of a WW Dynamical Scalar Resonance within a Chiral Effective Description of the Strongly Interacting Higgs Sector

Original · EN

We have studied the strongly interacting Wₗ Wₗ → Wₗ Wₗ I=L=0 partial wave amplitude making use of effective chiral Lagrangians. The Higgs boson is explicitly included and the N/D method is used to unitarize the amplitude. We recover the chiral perturbative expansion at next to leading order for low energies. The cases mₕ<< 4πv and mₕ>> 4 πv are considered in detail. It is shown that in the latter situation a state appears with a mass 1 TeV. This state is dynamically generated through the strong interactions between the Wₗ and is not responsible for the spontaneous electroweak symmetry breaking. However, its shape can be very similar to that of the mₕ 1 TeV case, which corresponds to a conventional heavy Higgs boson.
