Given the absence of any new physics signal at the Large Hadron Collider (LHC) so far, there is a growing interest in the community for the interpretation of LHC measurements in terms of effective field theories (EFTs). EFTs are supposed to parametrize in a general way leading deviations from the Standard Model with the underlying assumption that there is mass-gap between the weak scale and possible new degrees of freedom. Most of the efforts in this direction are focused towards the interpretation of Higgs-boson data, given its direct link with the electroweak symmetry breaking mechanism. In [1504.01707] a
parametrization of anomalous Higgs-boson couplings that is both systematic and practical was proposed. It is based on the electroweak chiral Lagrangian, including a light Higgs boson, as the EFT at the electroweak scale. This framework allows to describe sizable
deviations from the Standard Model in the Higgs couplings, of order 10%, considered to be parametrically larger than new-physics effects in the sector of electroweak gauge interactions.
