Abstract

In this PhD thesis, we study different supergravity backgrounds which correspond to dual field theories based on Gauge/Gravity correspondences. We calculate different properties and observables in the dual field theory, such as Wilson loops and mass spectra, using holographic methods, to shed light on t...

description In this PhD thesis, we study different supergravity backgrounds which correspond to dual field theories based on Gauge/Gravity correspondences. We calculate different properties and observables in the dual field theory, such as Wilson loops and mass spectra, using holographic methods, to shed light on the nature of the theories. Some of these setups are used in the context of composite Higgs models to address the Naturalness problem in the standard model of particle physics. First, we focus on holographic models for describing Higgs compositeness, both in the context of Higgs as a dilaton or as a pseudo-Nambu-Goldston boson of SO(5)/SO(4) symmetry-breaking pattern. Next, other supergravity backgrounds with asymptotic AdS6 or AdS5 factors in their geometry are studied, which are deformations of previously well-studied solutions. In their field theory duals, we establish that these deformations lead to a transition from conformal behaviour to confining or screening. A variety of observables are calculated in these backgrounds to assess the field theory properties.
