Many different extensions of the Standard Model have been proposed where the Higgs doublet is emerging as a bound state from a new physics strongly coupled sector: I discuss a general class of these models, recently reviewed in 1511.08218, where the new sector is an approximate conformal theory and the Higgs scalar experiences non trivial spectral properties, as a Higgs continuum, besides the...

We study the decay of a heavy Higgs boson into a light Higgs pair at one loop in the singlet extension of the Standard Model. To this purpose, we properly fully renormalized the extended Higgs sector of the model. We applied different schemes to calculate the heavy-to-light Higgs decay width H-> hh at next-to-leading order electroweak accuracy, and demonstrate that certain prescriptions lead...

The study of the stability condition of the Electroweak vacuum is an
essential tool for the comprehension of the non-perturbative
interplay between the Standard Model and its UV completions
at high energy (Planck) scales.
The role played by the IR parameters, such as Higgs and top masses,
on the stability analysis has been widely investigated.
In our contribution we show that the...

The complete effective chiral Lagrangian for a dynamical Higgs is presented together with the ultimate fit considering data from LEP and LHC. The comparison with the d=6 effective linear Lagrangian constructed with the Standard Model Higgs doublet is presented. A strategy for disentangling the Higgs nature is also discussed and it includes: i) anomalous signals potentially relevant for LHC...

We compute the flavour-changing top decays t-> ch and t-> cV (V =g ,Z) within the framework
of the aligned two-Higgs-doublet models. By exploiting constraints from flavour physics and the
measured Higgs properties, we investigate the parameter space of the model and its impact on the
associated branching ratios. It is observed that the Higgs signal strength in the di-photon channel
imposes...
