Associated to the scholarship:12/21436-9 - Hierarchical quiver Gauge theories: model building and phenomenology, BP.PD


This project is focused on model building and phenomenology of particle physics beyond the Standard Model. In particular, we will explore models of Composite Higgs and Cosmological Relaxation of the Electroweak scale and intend on building new models in these frameworks utilizing the technology of N-site theory space constructions. We plan to study the phenomenology of the resulting models, such as cosmological signatures and collider searches, making use of dedicated software packages as well as analytical calculations. (AU)
