Circa 95% of the universe is made of unknown forms of matter and energy, while to describe the remaining 5% one needs at least three fundamental forces, i.e. Quantum Electrodynamics (QED), Weak Interactions and Quantum Chromo Dynamics (QCD). Furthermore strong interactions are responsible for creating the bulk of the bright mass, i.e. the 5%. It is therefore natural to expect that to correctly...

We present some four-dimensional purely fermionic gauge theories that
give a UV completion of composite Higgs models. We start at the group theoretical level, addressing the necessary (but not sufficient) conditions for the viability of these models, such as the existence of top partners and custodial symmetry. We then study the dynamics of one of the most promising models, based on a SU(4)...

Assuming that mass scales arise in nature only via dimensional transmutation, we extend the dimension-less Standard Model by adding vector-like fermions charged under a new strong gauge interaction. Their non-perturbative dynamics generates a mass scale that is transmitted to the elementary Higgs boson by electro-weak and possibly Yukawa interactions. In its minimal version the model has the...

In this talk I study a simple, experimentally viable effective Lagrangian, the Custodial Vector Model with symmetries protecting the (composite) Higgs couplings and the values of the electroweak parameters - Essentially the 'degenerate-BESS' model with a Higgs state. I will use this model as a basis to discuss how underlying strong dynamics may give rise to SM Higgs like state at LHC....
