Abstract
This research project is divided into two main lines, unified in exploring the role of symmetry and possible mechanisms for breaking such symmetries in physics of elementary interactions. The first line investigates proposed modifications and/or violations of the relativistic symmetry, covering the theoretical consistency of these proposals and their possible phenomenological consequences. Typically these violations of relativistic symmetry are motivated by arguments of quantum gravity, and can bring very interesting consequences of the theoretical and experimental point of view. The second line investigates the mechanism of symmetry breaking in theories with scale invariance, in particular the improvement of the calculation of the effective potential via the renormalization group equation. This enhancement has been shown to induce significant impacts on a version of the standard model in which the classical theory presents scale invariance, and also in Chern-Simons theories in three-dimensional spacetime. We intend to extend these studies to supersymmetric models, as well as other proposed models for physics beyond the Standard Model. The fundamental objective is to investigate whether the break scenario symmetry of scale by radiative corrections may be, in fact, behind some of the Standard Model properties and their extensions.
