O’ Higgs where art Thou?<br />
A careful analysis of the different decay modes, and<br />
scattering amplitudes allowing to determine the nature of the<br />
Higgs is in order. We will use the effective Lagrangian<br />
approach in which a singlet state is added to the non-linearly<br />
realized SM Lagrangian featuring only the already<br />
discovered fields. We will then consider different limits, e.g.<br />
the case of the SM Higgs. This analysis is extremely<br />
important especially in view of the recent tantalizing<br />
experimental results released by the ATLAS and CMS<br />
collaborations. In fact, combining different channels ATLAS<br />
reported 3.6 standard deviations excess for a reference Higgslike<br />
state with a mass around 126 GeV. This analysis will help<br />
elucidate the nature of this state.<br />
By the end of 2012, depending on LHC performance, we<br />
might know if a particle similar to the SM Higgs boson has<br />
been discovered or excluded. Whatever the experimental<br />
outcome will be novel dynamics can play a fundamental role.<br />
This is so since there are a number of theoretical drawbacks<br />
with accepting the existence of a SM Higgs. For example a<br />
SM Higgs with a mass around 126 GeV might render the<br />
vacuum of the electroweak sector unstable at high energies,<br />
implying that the SM is an inconsistent theory.<br />
Higgs: Elementary or Composite?<br />
We will investigate a near-conformal (composite) nature of<br />
the Higgs. Here the Higgs is naturally identified with the<br />
state saturating the dilatonic current of the fundamental<br />
