The claimed finding of a light Higgs boson makes the minimal Standard Model unitary. Yet, we recall that the general low-energy dynamics for the minimal electroweak symmetry breaking sector with three Goldstone bosons and one light scalar is not so. We construct the effective Lagrangian for these four particles and their scattering amplitudes, that can be extracted from LHC experiments when longitudinal W, Z modes be properly isolated for E >> M-W (equivalence theorem). We then observe the…

Strongly Interacting Electroweak Symmetry Breaking Sector with a Higgs-like light scalar
The apparent finding of a 125-GeV light Higgs boson closes unitarity of the minimal Standard Model (SM), that is weakly interacting: this is an exceptional feature not generally true if new physics
Fingerprints of heavy scales in electroweak effective Lagrangians
A bstractThe couplings of the electroweak effective theory contain information on the heavy-mass scales which are no-longer present in the low-energy Lagrangian. We build a general effective
Integrating out resonances in strongly-coupled electroweak scenarios
Accepting that there is a mass gap above the electroweak scale, the Electroweak Effective Theory (EWET) is an appropriate tool to describe this situation. Since the EWET couplings contain information
Resonant production of Wh and Zh at the LHC
A bstractWe examine the production of Wh and Zh pairs at the LHC in the context of a Strongly Interacting Symmetry Breaking Sector of the Standard Model. Our description is based on a non-linear
One-loop WLWL and ZLZL scattering from the electroweak Chiral Lagrangian with a light Higgs-like scalar

Electroweak chiral Lagrangian with a light Higgs and $\gamma\gamma\to Z_L Z_L, W_L^+ W_L^-$ scattering at one loop

The Strongly-Interacting Light Higgs
We develop a simple description of models where electroweak symmetry breaking is triggered by a light composite Higgs, which emerges from a strongly-interacting sector as a pseudo-Goldstone boson.
Longitudinal WW scattering in light of the “Higgs boson” discovery
WW scattering is dominated at high energies by their longitudinal components, which are the most sensitive to the nature of the electroweak symmetry breaking. Prior to the discovery at the LHC of a
Distinguishing the higgs boson from the dilaton at the large hadron collider.
TLDR
The prospects for distinguishing this mode from a minimal Higgs boson at the LHC and ILC are discussed, and the main discriminants between the two scenarios are (i) cubic self-interactions and a potential enhancement of couplings to massless SM gauge bosons.
Strong double higgs production at the LHC
The hierarchy problem and the electroweak data, together, provide a plausible motivation for considering a light Higgs emerging as a pseudo-Goldstone boson from a strongly-coupled sector. In that
