In these proceedings we provide a brief summary of the findings of a previous article where we have studied the photon-photon scattering into longitudinal weak bosons within the context of the electroweak chiral Lagrangian with a light Higgs, a low-energy effective field theory including a Higgs-like scalar singlet and where the electroweak would-be Goldstone bosons are non-linearly realized. We consider the relevant Lagrangian up to next-to-leading order in the chiral counting, which is…

Higher order QCD predictions for associated Higgs production with anomalous couplings to gauge bosons
A bstractWe present predictions for the associated production of a Higgs boson at NLO+PS accuracy, including the effect of anomalous interactions between the Higgs and gauge bosons. We present our

Light 'Higgs', yet strong interactions
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
Viability of strongly coupled scenarios with a light Higgs-like boson.
A one-loop calculation of the oblique S and T parameters within strongly coupled models of electroweak symmetry breaking with a light Higgs-like boson is presented, and the experimentally allowed range forces the vector and axial-vector states to be heavy, with masses above the TeV scale, and suggests that the H boson should have a WW coupling close to the standard model one.
Anomalous gauge couplings of the Higgs boson at high energy photon colliders

Effective theory of a dynamically broken electroweak Standard Model at NLO
A bstractWe consider the Standard Model as an effective theory at the weak scale v of a generic new strong interaction that dynamically breaks electroweak symmetry at the energy scale Λ ~ (few) TeV.
Radiative corrections to WL WL scattering in composite Higgs models
The scattering of longitudinally polarized electroweak bosons is likely to play an important role in the elucidation of the fundamental nature of the Electroweak Symmetry Breaking sector and in

A bstractThe pattern of deviations from Standard Model predictions and couplings is different for theories of new physics based on a non-linear realization of the SU(2)L × U(1)Y gauge symmetry
