The Standard Model (SM) of Particle Physics is an extremely good description of the experimental data we have today. However, it has apparent limitations, due to its significant number of arbitrary parameters. In addition, in the light of the SM, the electroweak scale is unstable, which leads to the Hierarchy Problem. The solution to this problem requires new advances in physics in the Tev scale, which is precisely the energy scale being explored in CERN's Large Hadron Collider (LHC). In this project we will study new extensions of the SM that describe physics in the TeV scale.Since the appearance of the Higgs Boson in 2012, the spectrum of the SM has been completed. In light of this, there are two main lines of reasoning for solving the Hierarchy Problem: if the Higgs boson is fundamental, the supersymmetry must be present in the Tev scale. Otherwise, the Higgs Boson is a bound state. In this project, we will focus on the second line of reasoning.In general, composite Higgs models require the existence of new particles in the TeV scale. That's because in such theories the Higgs is a pseudo Nambu-Goldstone boson (pNGB) as a result of a spontaneous symmetry breaking, and thus these new states follow from this new symmetry. The lack of observation of these states, specially at the LHC, is a problem of composite Higgs models. However, the phenomenology associated with the Higgs boson is well defined. This will be the focus of this project: study the theoretical basis and the phenomenology of these models, particularly in scenarios that require high luminosity to be studied.
