- Studying of renormalization group and dynamical symmetry breaking in supergravity, BP.PD
Abstract
Studying effective potentials is an important tool to understand, through classical concepts, the quantum behaviour of physical systems. Moreover, effective potentials are a natural way to study spontaneous symmetry breaking. Even though Supersymmetry is one of the most discussed proposals of physics beyond the standard model, to construct realistic models of particle physics, Supersymm...
- Dynamical supersymmetry breaking and noncommutative quantum field theory, BP.PD
Abstract
The presence of divergences is certainly one of the main characteristics of the quantum field theory. A way to treat these divergences is through the use of renormalization methods, another one is to look for finite quantum field theories. The hope to find such theories is strong related with Supersymmetry, that improves the ultraviolet behavior of the theories due to a cancellation bet...
